Ball bearing bearing VULKOLLAN®

radialpolymercombined

-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.
