High Temperature Bearings

Unasis High Temperature Catalogue »

The Unasis range of high temperature bearings provide a high quality solution to applications which are normally beyond the range of standard bearing products. The high temperature range includes equivalents to the SNR and SKF ranges but with quick availability and strong performance characteristics.

Applications

High Temperature Bearings

  • Textile machinery.
  • Heater units / fan assemblies.
  • Driers.
  • Alternators.
  • Industrial ventilation.
  • Hi temperature ovens and kilns

Product Types:

150-2RS – 6000, 6200 and 6300 series (equivalent to SNR FT150)

Features

  • C4 radial cage.
  • Grease and rubber seals for working at 150ºC.

270-Open – 6000, 6200 and 6300 series (SNR F600, SKF VA201)

Glass-Manufacturing

Features:

  • For temperatures of up to 270ºC.
  • 52100 (100Cr6) bearing steel construction with heat stabilisation
  • Increased radial clearance.
  • Manganese phosphate on all surfaces
  • Molybdenum disulphide coating
  • Klüber grease lubrication
  • Open type

Recommended Use:

  • Temperatures of up to 270ºC.
  • Low rotation speed: Max 100 revs per minute.
  • Easy maintenance installations.
  • In areas where dirt is not excessive and where frequent maintenance can be carried out (re-lubrication).
  • Maximum load permitted: 75% of the nominal load at maximum temperature.
  • Average maximum humidity level: 65%.

270-ZZ 6000, 6200 and 6300 series (SNR F600, SKF VA208)

High Temperature Bearings

Features:

  • Maintenance-free ball bearings.
  • Construction in C6 stabilised steel.
  • Increased radial clearance.
  • Manganese phosphate on all surfaces.
  • Grease with KLUBER BARRIETA LT55/2.
  • Ball bearings with ZZ protection.

Recommended Use:

  • Temperatures of up to 270ºC
  • Medium rotation speed: maximum 1.000 revs per minute
  • Maximum permitted load: 75% of the nominal load at the maximum permitted temperature.
  • Installations where maintenance is difficult.
  • Ideal in installations where cleanliness is obligatory. Bearing grease is white in colour and periodical re-lubrication is not necessary.
  • Medium high level of atmospheric humidity: maximum 70%.

330-Open 6000, 6200 and 6300 series

Kiln-Car-Bearings

Features

  • 52100 (100Cr6) bearing steel construction with heat stabilisation
