For economical designs in machines, lifting and handling systems.

Advantage of the WINKEL Bearing system:

  • Reduces your designing and production costs
  • Can take up high radial and axial loads
  • Strong profiles for high stat. and dynamic loads
  • Best dispersion of forces in the profiles
  • Longer lifetime for bearings and profiles
  • Economical assembling by welding bolt
  • Bearing components are easily exchangeable

Technical details:

  • Outer rings are made from case-hardened steel UNI 16 CrNi 4 hardened at 62+2HRC
  • Inner rings are made from bearing steel En 31-SAE 52100 hardened at 62-2 HRC
  • Cylindrical rollers have flat ground heads, made from En 31-SAE 52100 steel hardened at 59 – 64 HRC
  • Welding bolts are made from C22E (Material no. 1.1151)
  • Bolt tolerance –0.05 mm
  • Bearings from 4.054 to 4.063 are relubricateable
  • Bearings are lubricated with grease grade 3 (e.g. Shell Gadus S2 V100 3)
  • Standard WINKEL Bearings are resistant from -20 °C to +80 °C
  • WINKEL High Temperature Bearings can be used at max. +250 °C environmental temperature.
  • The max. speed for WINKEL Bearings in steel version is 3m/s.
  • For VULKOLLAN® and POLYAMIDE kind of bearings is the max. speed 6 m/s.
  • The clearance between axial bearing and inner side of the profile should not exceed 0,5 mm.
