Hardened bushing without slit with lubrications grooves

Hardened clamp bushing

Hardened sliding bearings are primarily used when the dynamic load breaks and rapidly wear out sliding bearing made of steel or bronze. These bearings must be lubricated. The hardness of the material is 58-92 HRC and require a shaft hardness of at least 62 HRC to avoid wear on the shaft.

Bearings of type BGFR has a circular diagonal lubrication groove inside, and around the outside circumference in the middle sector. The outside lubrication groove has a through-going lubrication hole.
