This insert bearing carries a spherically ground outer ring, locked onto the shaft by an eccentric locking collar with thread designation m = M 6 x 0,75. The inner ring is extended on both sides, a design intended for constant rotation direction only. Bore diameter d is 25 mm, weight is 0,25 kg. Further dimensions read from the catalogue drawing: B = 44,3, C = 15, D = 52, c = 14,0, s = 17,4, c0 = 7,8, d1 = 33,8, d2 = 38,1. The double-sided sealing keeps the pre-packed lithium grease class 2 inside the housing and blocks contaminants from entering along the shaft. The eccentric collar locking allows quick mounting directly on the shaft without additional adapter sleeve, provided the rotation direction stays constant as intended by the double-side extended inner ring. Dimension B, C and D can be taken directly from the catalogue drawing for housing and shoulder clearance checks. The dimensional and constructional equivalent listed for this bearing is SKF YEL 205.
