Options for type R-40: roller guides, rakel, bumper. For wheel blocks with volkollan wheels see drawings of steel versions.

Dimensions

  • For the dimension of bearing and profile, the maximum allowable load F [N] max. stat. should be confirmed.

Relubrication

  • Our Winkel bearings are full complement cylindrical rollers which are lifetime lubricated for one shift and unsteady operation. Due to many years of experience we can assure you that for these kinds of use there will be no reduction of lifetime at normal applications.
  • For applications such as for example in warehouses and machine halls a light surface conservation with commercial spray oil will be sufficient and in addition, a regular relubrication every 6 months.
  • For extension of life-time the Winkel bearings 4.054 up to 4.063 are relubricateable. Generally, the relubrication holes are closed with threaded plugs M6. The bearings are delivered without grease nipple.

    In case of special environmental conditions such as dust, incur of dirt, moisture, outdoor operations, temperatures over 40 degrees, frequent load changes (continuous operation) and heavy duty the bearings should be relubricated at least one time per month. For this we would recommend to you to use our lubrication system Winkel Combi-Lub 1 or a central lubrication system.
    Bearings are lubricated with grease grade 3 (e.g. Shell Gadus S2 V100 3)

Working up

  • For welding operations on WINKEL Bearings with a diameter less than 100 mm, all bearing components must be disassembled.

    WINKEL Bearings with an outer diameter more than 100 mm should be welded on both sides of the bolt.

    After the assembling of the bearings, or after the adjusting operation, the front side screws should be secured with loctite.

    To avoid cracks in the welded joints please use welding electrodes and cored wire for unalloyed steel. For example electrode: E 42 5 B 42 H 10 according DIN EN 499. For example cored wire: T 42 4 B C 3 H5 / 7 42 4 B M 3 H5 according DIN EN 758.
  • Jumbo WINKEL Bearings should be welded on both sides of the bolt.
  • The guide ways in the profiles should be lightly greased and not painted.

Special designs

  • Special bolts are available for WINKEL Bearings of type (PR) 4.072 (P) to (PR) 4.080 (P).

System solutions

  • We construct and manufacture complete lift- and handling units according to customer needs. Constructions with CAD and a progressive production enables high flexibility in achieving complete solutions in the field of handling systems and automation.

Tolerances

  • For all not tolerated dimensions counts ISO 2768 - m

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.

Corrosion protection for profiles

All WINKEL profiles are available in corrosion protected version. We deliver your profiles completely machined and galvanized ready to mount.
Following coating are available:

Chemical galvanized

  • All steel profiles with lengths up to 3 m are available in white or yellow galvanized version on request.

Plasma galvanizing

  • All WINKEL profiles with lengths up to 12 m are available in plasma galvanized version. Completely welded constructions with our profiles are available in coated version, independent from their size. Plasma galvanized surfaces are superior to normal zinc coatings. The thickness of the coatings vary from 0,1 to 0,3 mm dependent of the use in land- or offshore atmosphere.
    The usage of WINKEL Bearings on the raceway do not crack off the coating.
