SUPER BALL BUSHING The original self-aligning, precision, anti-friction linear bearing with load capacities up to 4,000 lbf, and speed up to 10 ft/sec (3 m/s). Available in closed, adjustable, and open styles, both single and twin versions in a large selection of sizes.
- A self-aligning capability up to .5 degrees compensating for inaccuracies in base flatness or carriage machining.
- The Round Rail* Advantage combined with the self-aligning feature, eliminating the need for derating factors commonly required for linear guides.
- Travel speeds up to 10 ft/s without a reduction in load capacity.
- Light-weight, wear-resistant, engineered-polymer retainers and outer sleeves which reduce inertia and noise.
- Radically floating bearing plates. When installed in an adjustable housing, the Super Ball Bushing Bearing may be adjusted to a specific diametrical fit-up for accurate and repeatable movement.
- A constant coefficient of friction as low as .001.
- The use of smaller, less expensive drive motors, belts, linkages, gears, and ball screws when replacing high friction plain bearings.
- A closed configuration for end supported applications and an open configuration for continuously supported applications.
- Ready-to-install pillow blocks with double acting seals and an access for lubrication: minimal installation and downtime.

PRECISION STEEL BALL BUSHINGS
Well known as A-bearings, these all-steel bearings are the original precision anti-friction linear ball bushing bearings offering the following features:
- A coefficient of friction as low as .001. When replacing high friction plain bearings, Precision Steel Ball Bushing bearings dramatically improve machine productivity and efficiency.
- All-steel construction, for maximum system rigidity.
- Two accuracy classes allowing for immediate improvements in system positioning and repeatability.
- Available in fourteen bore sizes and nine configurations.
- The RoundRail* Advantage, minimizing installation time and cost.
- Steady state travel speeds up to 10 ft/s and accelerations to 450 ft/s2 without the use of derating factors.
- An operating temperature up to 600 degrees F.
- Available in a self-aligning pillow block housing for ease of installation and use

MULTITRAC BALL BUSHING BEARINGS These bearings offer a patented multiple-track design. Sizes available from 8 mm to 40 mm with load capacities up to 9,250 N. Thomson MultiTrac Ball Bushing Bearings offer:
- Patented, multiple-track design with up to twice the load carrying capacity, or 8 times the life, of conventional linear bearings.
- Rigid design for minimal deflection assuring accurate, precise positioning.
- Coefficient of friction as low as 0,001.
- Patented ball control technology which eliminates binding and chatter (stick-slip) common to high-friction, plain bushings and sliding-way bearings.
- RoundRail* Advantage which, combined with the advanced MultiTrac Ball Bushing* bearing design, eliminates the need for the derating factors commonly required with square rail linear guides.
- Steady state speeds up to 3 m/s and accelerations up to 150 m/s(2), without the use of derating factors.
- Wear-resistant, engineered-polymer retainers to reduce inertia and noise levels.
- Available in a stainless steel (440C) corrosion resistant option
- Adjustable, closed and open configurations.

XR - EXTRA RIGID BALL BUSHINGS
These XR Ball Bushing Bearings offer high load capacity and extreme rigidity combined with the RoundRail Advantage. Features include:
- Five times the load capacity or 125 times the travel life of conventional linear bearings. This dramatic increase in travel life reduces downtime and maximizes productivity.
- Three times the rigidity of conventional linear bearings, immediately improving machine positioning accuracy and repeatability.
- The RoundRail* Advantage combined with travel speeds up to 5 ft/s. Derating factors commonly found in linear guide products are eliminated.
- Ease of maintenance. When normal maintenance requires bearing replacement, XR Ball Bushing bearings can be quickly and cost-effectively replaced without scrapping the entire system - another shortcoming of some linear guides.
- Double acting seals at both ends to keep out contamination and retain lubrication.
- Lasting precision alignment by combining the non-wear characteristics of the XR Ball Bushing bearing with a rigid ductile iron pillow block
- High accelerations and operating speeds without a dramatic increase in the power consumption commonly seen with high friction v-way and flat-way systems
- Available in 3 sizes

ACCESSORIES
Hollin Applications offers a complete line of accessories for our extensive offering of linear bearing products.
- Internal Retaining Rings - push-in retaining rings are for use with Super Smart, Super and Precision Steel Ball Bushing* closed type bearings. Each retaining ring is installed inside the housing bore at each end of the Ball Bushing bearing.
- External Retaining Rings (Type W) - fit into the retaining ring grooves on the outside diameter of Super Smart, Super and Precision Steel Ball Bushing bearings to provide external mounting retention. Available in standard and stainless steel versions.
- External Retaining Rings (Type C) - fit into the retaining ring grooves on the outside diameter of Super Smart, Super and Precision Steel Ball Bushing bearings (Open and Closed Type) to provide external mounting retention. Available in standard and stainless steel versions.
- External Seals for Fixed Diameter Housings - double acting seals for Super Smart, Super and Precision Steel closed type Ball Bushing bearings. Standard and stainless versions available. Sizes 1 1/2 inch and above use spring fingers to reinforce sealing capability which could add to seal drag.
- External Seals for Adjustable Housings - double acting seals for Super Smart, Super and Precision Steel Ball Bushing bearings. Seals have a radial slot through the circumferences to facilitate diameter adjustment. Standard and stainless steel versions available.
- External Seals for Open Type Housings - double acting seals for Super Smart, Super and Precision Steel Ball Bushing Open Type bearings. Standard and stainless steel versions available.
- Integral Seals for Sealed Super Ball Bushing Bearings (Closed Type) - double acting replacement seals for the Sealed Super Ball Bushing bearing.
- Integral Seals for Sealed Super Ball Bushing Bearings (Open Type) - double acting replacement seals for the Sealed Super Ball Bushing bearings.
- Integral Felt Seals for Closed Type Ball Bushing Bearings - felt seals for Super Smart, Super and Precision Steel closed type Ball Bushing bearings. Felt seals reduce drag for applications where reduced friction is critical. Felt seals provide minimal protection from the ingress of contamination. Use PR type external retaining rings for retention.
- Integral Seals for RoundWay* Linear Roller Bearings - standard seals for both single and dual types.

SUPER SMART BALL BUSHING PILLOW BLOCKS
To minimize installation time and cost, the Super Smart Ball Bushing bearing can be ordered factory-installed in an industry standard single or twin pillow block. The closed type pillow block is used in end supported applications for spanning or bridging a gap. The open style is used in continuously supported applications when maximum rigidity and stiffness is required. Each Super Smart Pillow Block is complete with integral double acting seals which keep out contaminants, retain lubrication and maximize bearing life. Since each pillow block is dimensionally interchangeable with the industry standard Thomson Super Ball Bushing Pillow Block, system performance improvements can be realized immediately. |
