Roundway Roller Bearings

RoundWay® Roller Bearings

Thomson invented the RoundWay Linear roller bearing for use in high load, heavy duty applications. The RoundWay roller 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.  The chain-connected rollers allow the RoundWay to travel at extremely high speeds in unforgiving, contaminated environments.
