Accuracy:JIS B 1558
JIS B 1514
JIS B 1559
Bearing Inner Diameter Tolerance: H7 (Clearance Fit)
Only PDRCP, J7 (Transition Fit)
Operating Temperature: -15 ~ +100°C
Grease Fitting Nominal Diameter: 1/4 to 28 UNF (Unified Standard)
Ball bearing moves slightly due to self-aligning function.
For PDRCP, the fit between the main body and the bearing is designed to be slightly tight to maintain transition fit.
If the bearing is skewed upon delivery, insert the shaft or similar into the bearing and adjust the inclination.
The lubrication-free version comes pre-filled with the correct amount of grease, and no lubrication is required for usage under normal conditions.
