Documents Drawing Description Specifications Item #: RNU 204 Item Name: Single Row, without an Inner Ring Cylindrical Roller Bearings Principal Dimension F w : 1.063 in Principal Dimension D: 1.8504 in Principal Dimension C: 0.5512 in Basic Dynamic Load Ratings C: 3310 lbf Basic Static Load Ratings C 0 : 1650 lbf Speed Ratings - Reference: 18000 rpm Speed Ratings - Limiting: 19000 rpm General Description Roller end / flange contact area SKF cylindrical roller bearings have two integral flanges on either the inner or outer ring to guide the rollers. The bearings have "open" flanges, i.e. the inward face of the flange is inclined by a defined angle. The flange design, together with the roller end design and surface finish, promote the formation of a lubricant film to reduce friction and frictional heat. Logarithmic roller profile The roller profile determines the stress distribution in the roller/raceway contact area. As a result, the rollers in SKF cylindrical roller bearings have a logarithmic profile to distribute loads evenly along the rollers. This prevents peak stresses at the roller ends to extend bearing service life. The logarithmic profile also reduces sensitivity to misalignment and shaft deflection. Surface finish The surface finish on the contact surfaces of the rollers and raceways maximizes the formation of a hydrodynamic lubricant film and optimizes the rolling motion of the rollers. The benefits derived from this, compared with traditional designs, include enhanced operational reliability. Interchangeable components The separable components of same-sized SKF cylindrical roller bearings are interchangeable. Any bearing ring with a roller and cage assembly can be assembled with any removable ring of the same bearing type and size having the same internal clearance class. This is particularly important when bearings and their components must be mounted independently of each other.
