Request Information
Blind Hole Fixing type (RBHJ) allows mounting into a solid machine base where through mounting holes are not possible, or where the thickness of the mounting plate is too great. The Blind Hole Fixing type is also useful where adjustment from the front is preferred or where access to the opposite side of the mounting hole is restricted. They are available in Concentric (C) which are fixed, or Eccentric (E) which are adjustable.
All bearings are greased for life internally. Customers are strongly advised to provide lubrication to the interface between bearings and ring slide by specifying HepcoMotion Lubricators or Bleed Lubrication system. Lubrication greatly increases load capacity and life.

Manufacturing Notes

N/A For Dimension O: It is recommended that holes to suit bearing mounting studs should be reamed to tolerance F6 for a sliding fit.
For 2: Nuts and washers are supplied with both concentric and eccentric RSJ/RLJ type bearings.
For Dimension N & R: 'N' is the eccentric offset due to the double eccentric design (2 x N = total stroke). R dimension is both the eccentric offset of the adjusting nut and total stroke at the bearing centerline.
For Dimension B1: Controlled height (CHK) bearings are selected in ±0.010mm bands in respect of the B1 dimension. They are supplied in sets of up to 50 parts as standard, with larger sets on request.
For 5: For adjusting tool part numbers see table. For adjustment procedure and fixing nut tightening torques see 58.
For 6: Fasteners for the through fixing type bearings are black on the concentric version and bright zinc plated on the eccentric version for identification purposes, except stainless steel type.
For Nitrile Seals : Stainless steel bearings are only a
