Linear Ball Bearings

Thomson invented the linear ball bushing bearing over 60 years ago. We’ve been the recognized leader in linear ball bearing technology ever since. The widest range of linear ball bearings and accessories, all engineered for low friction and smooth, accurate straight-line motion – we satisfy strict requirements with the highest-performance linear ball bearings available. And, Thomson linear bearings used with Thomson 60 Case® Shafting boost shafting life by up to 50%.

What makes Thomson's linear ball bearings superior?

Our linear bearing products are part of an unmatched portfolio of motion technologies available as components through to complete custom systems. As such we provide the optimal motion solution without technology bias. Performance is built into our entire line of linear bearing products:

Super Linear Ball Bushing® Bearing

Thomson Super Linear Ball Bushing® Bearing plates allow carriage machining, thanks to defined radius crowns for maximized self-alignment accuracy. The Super Ball Bushing Bearing has been the industry standard for self-aligning linear bearings for over twenty years. This bearing provides three times the load capacity or 27 times the travel life of conventional linear bearings. Our Super Linear Ball Bushing Bearings and pillow blocks are our original self-aligning precision anti-friction linear bearings.

Super Smart Linear Ball Bushing® Bearings

Our Super Smart Linear Ball Bushing® Bearings and pillow blocks use patented self-aligning, double-track linear bearing technology – which doubles the load carrying capacity and increases travel life by eight times. 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.

Our Precision Linear Ball Bushing Bearings meet highly specialized demands:

Precision Steel Linear Bearings

Precision Steel linear bearings eliminate binding and chatter in high-temperature environments. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson Pillow Block, the Precision Steel Ball Bushing bearing can self-align up to 3° in all directions.

MultiTrac® Linear Bearings

MultiTrac® linear bearings boast a patented, multiple-track rigid design that minimizes deflection for accurate, precise positioning. The bearing's patented ball control technology eliminates binding and chatter (stick-slip), common with high friction, plain bearings.

Miniature Instrument Linear Bearings

Miniature Instrument linear bearings are made for high accuracy instrumentation applications where compact size is required, and for small mechanisms or devices that require high repeatability and responsiveness. When replacing high friction plain bearings, Instrument bearings consistantly low coefficient of friction eliminates stick-slip and provides smooth linear performance. Each Instrument bearing can be provided with a matched 60 Case LinearRace shafting for minimum fit-up, optimizing system performance and accuracy.

Specialty linear bearing solutions such as RoundWay linear rollers and FluoroNyliner bushings are for specific applications:

RoundWay® Linear Bearings

RoundWay® linear bearings are a low-friction roller that offers high performance in highly contaminated environments. The RoundWay bearing combines the high load capacity of hardened and ground steel recirculating rollers with a rigid malleable iron mounting block providing high load capacity with smooth linear travel.

FluoroNyliner® Bushing Linear Bearings

FluoroNyliner® bushing linear bearings are recommended for washdown, contamination or submerged environments. Its large contact surface area gives it excellent performance in high vibration or impact applications, while its simplified design allows it to run in highly contaminated environments.
