✦ Raceway geometry – The single raceway features a V-shaped profile with a 90° included angle, guiding rollers into precise orthogonal contact with both axial and radial thrust surfaces.
✦ Roller composition – Rollers are manufactured from through-hardened GCr15 bearing steel with a surface hardness of 60–64 HRC and a length-to-diameter ratio of 1.2:1.
✦ Gear tooth specification – Internal gear teeth conform to DIN 3962 grade 6, with a 20° pressure angle and a tip relief modification of 0.02–0.04 mm to optimize meshing under load.
✦ Ring flatness tolerance – Mounting faces are ground to a flatness of 0.02 mm over the entire ring circumference, ensuring even bolt loading and seal compression.
✦ Seal groove dimensions – Seal channels are machined to a depth of 4.5 mm and a width of 3.2 mm, sized for standard profile seals with a lip interference of 0.6 mm.
✦ Bolt hole geometry – Mounting holes are countersunk with a 90° chamfer and positioned on a bolt circle diameter with a positional tolerance of 0.1 mm.
