RSHP Roller runner block made of steel

Characteristic features
▶ RSHP roller runner blocks are suitable for all typical applications as well as for special installation and environmental conditions and conditions of use,
so that additional special designs are not necessary.
▶ High torque load capacity
▶ Same high load capacity in all four directions of loading
▶ Maximum rigidity in all load directions due to additional screw connections on two bore holes in the center of the roller runner block
▶ Unrestricted interchangeability
▶ All roller guide rail versions can be combined arbitrarily with all roller runner block versions
▶ Accessories can be screwed down to the front of the roller runner block.

Dimensional Drawing and Specifications


		a) For O-ring Size 25: Ø 5 · 1.5 (mm) Sizes 35 to 65: Ø 7 · 1.5 (mm) Open lube port if necessary (see section entitled "Lubrication"). b) Recommended position for pin holes (E4 dimensions, see section entitled "Instruction for mounting", segment "Pinned fitting"). Pre-drilled holes may be present at this position for manufacturing reasons. They are suitable for drilling out. c) Lube nipple, thread M6 – 8 deep: Connection is possible on all sides (at front and top for size 25). Dimensions differ among different connectors. d) For roller guide rails of accuracy class H, this base area may be without a groove for manufacturing reasons. e) Sealing plugs may be present at this position for manufacturing reasons. Remove before mounting. f) Runner blocks size 55 and 65 without coating and AS seal.

1) Determination of the dynamic load capacities and load moments is based on a stroke travel of 100,000 m according to DIN ISO 14728-1.
However, often only 50,000 m is actually stipulated. For comparison: Multiply values C, M_t and M_L from the table by 1.23.
