Conveyor Bearing CB-HM

Conveyor Bearing CB-HM
ISUTAMI CB-HM conveyor bearing combines of ball bearings and outer steel ring by stamping process. The mounting inner ring of CB-M conveyor bearing is round, while the mounting inner ring of CB-HM conveyor bearing is hexagonal. The flange length of CB-HM series bearing is smaller than the flange length of  CB-M series.

CB-M series transmission bearing, the inner mounting diameter (d) range is 0.252''-0.48'', outer ring diameter (D) range is 1.281''-1.872'', outer ring length (B) is 0.34''-0.42'', and the overall diameter (F) range is 1.38''-2.0''. Like the CB-A series transmission bearings and CB-B series transmission bearings, this series of bearings have a flange on one side and the flange length (C) is in the range of 0.17''-0.24''.

Conveyor Bearing CB-HM Features

CB-HM series transmission bearing, the mounting inner diameter (d) range is 0.252''-0.446'', outer ring diameter (D) range is 1.281''-1.872'', outer ring length (B) is 0.34 ''-0.42'', and the overall diameter (F) range is 1.38''-2.0''. Like the CB-HA series transmission bearings and CB-HB series transmission bearings, this series of bearings has a flange on one side and the flange length (C) is in the range of 0.17''-0.22''. In general, the bearing ball diameter of CB-HM series is the same as that of CB-M series, and the dimensional data of the same specification between these series is basically the same.

The conveyor bearings are inserted into the roller tube along with the shaft and placed in the frame. The roller rotates and the belt rides on top of the roller carrying the product. The belt can also be used under the drum to rotate the wheel and carry the products. This kind of bearing is usually used for low speed, high loading, corrosion, high temperature situation. Non-precision conveyor bearings may be sufficient when speed and load requirements are low or medium. When you need high speed or heavy loads, you need precision bearings that are normally shielded and sealed to prevent contaminants from entering the bearings. ISUTAMI CB series has a one-piece, precision machined outer ring to prevent any spreading or splitting under load. Hardened raceways improve anti-friction performance. ISUTAMI can also manufacture the bearings according to drawing and specification from customer.
