Thomson SPM12WW is a Super Ball Bushing linear bearing in the metric closed series, built for a 12 mm round shaft. Shaft Diameter: 12 mm. Outside Diameter: 22 mm. Length: 32 mm.
SPM — Thomson Super Ball Bushing bearing, metric closed type.
12 — nominal shaft diameter, 12 mm.
WW — integral wipers at both ends.
Dynamic Load Capacity: 830 N, based on a rated travel life of 100 km. Static Load Limit: 910 N. Number of Ball Tracks: 5. Item Weight: 0.02 kg. Maximum Temperature: 85°C (185°F). Design: self-aligning, closed, for end-supported shafts.
The bearing presses into a 22 mm housing bore and runs on a 12 mm hardened shaft. Overall length is 32 mm.
Carton form: SPM-12-WW. The Thomson SPM12 and SPM12W executions differ in seal or wiper configuration.
Thomson’s cross reference sheet lists these 12 mm closed, two-wiper bearings against the SPM12WW: Bosch Rexroth R0670 212 40, SKF LBCD 12 A-2LS, INA KN12-B-PP (earlier KN 1232-PP), NB TK 12 UU and Samick LMES 12 UU.
