Dimensional Drawing and Specifications


		a) For O-ring Size 15: Ø 4 · 1.0 (mm) Size 20 – 45: Ø 5 · 1.0 (mm) Open lube port if necessary (see section entitled “Lubrication”). b) Recommended position for pin holes (dimension E₄ see chapter Mounting) Pre-drilled holes may be present at this position for manufacturing reasons. They are suitable for drilling out. c) Lube nipple, size 15 – 20: Funnel-type lube nipple DIN 3405-A, M3x5, B₂ = 1.6 mm When using different lube nipples, pay attention to the screw-in depth of 5 mm! Lube nipple, size 25 – 45: Hydraulic-type lube nipple DIN 71412-A M6x8, B₂ = 9.5 mm When using different lube nipples, pay attention to the screw-in depth of 8 mm! The lube nipple is included in the scope of delivery (not installed). Connection is possible on all sides. d) Sealing plugs may be present at this position for manufacturing reasons. Remove before mounting.

2) Dimension H₂ without cover strip
3) Load ratings and load moments for ball runner block without ball chain. Load ratings and load moments for ball runner block with ball chain Page.12
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.
Often only 50,000 m are actually stipulated. For comparison: Multiply the values C, M_t and M_L by 1.26 according to the table.
