Bearings
Through Hole Fixing type is available in two stud lengths covering most thicknesses of mounting plate, the short version being used in HepcoMotion carriages. Both are available in Concentric (C) which provides a datum for the system, and Eccentric (DE) to provide enough adjustment to permit disengagement of a carriage or ring encircled by bearings 58.
All bearings are available in a Controlled Height version (CHK) which minimizes variation in the B1 dimension*4 desirable in high precision applications and is recommended whenever Double Row Bearings are used.
. This is
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 37 or Bleed Lubrication system 52. Lubrication greatly increases load capacity and life.
