This insert bearing carries a spherically ground outer ring locked onto the shaft by an eccentric locking collar, with the inner ring extended on both sides. This mounting method fixes the bearing for one constant direction of rotation. Bore-side data is limited to the reference symbol HC 100; any dimensional figures for L, H1 and similar callouts should be read off the drawing on the product card. Both sides of the bearing are sealed, and the unit is factory-filled with lithium grease class 2, so no separate lubrication step is required before installation. The spherical outer ring surface allows the housing seat to accommodate slight shaft misalignment during mounting. The eccentric locking collar provides a simple radial clamping method onto the shaft but requires the shaft to always turn in the same rotational sense. The dimensional and constructional equivalent listed for this bearing is SKF YEL 100.
