High-temp Track Rollers are especially modified and coated bearings with increased radial clearance. These products are usually used in applications with very high temperatures and slow speeds.
GSWC offers three different greasing options as standard:
HT1
GSWC High-temp Deep Groove Ball Bearings with the suffix HT1 are filled with a high-temp paste,
which hardens after reaching a certain temperature and leaves a powder.
Bearings lubricated with HT1 are suitable for slow speeds and temperatures up to 350°C,
but have to be relubricated or replaced after 12 to 18 months depending on the application.
HT2
GSWC High-temp Deep Groove Ball Bearings with the suffix HT2 are filled with a special grease.
Bearings lubricated with HT2 are suitable for slow speeds and temperatures up to 280°C.
Depending on the application, these bearings allow maintenance-free operation up to 5 years.
HT2X
GSWC High-temp Deep Groove Ball Bearings with the suffix HT2X are filled with a special grease.
Bearings lubricated with HT2X are suitable for slow speeds and temperatures up to 320°C.
Depending on the application, these bearings allow maintenance-free operation up to 5 years.
All High-temp Track Rollers come with the following benefits:
Increased radial clearance (multiple of C5)
as compensation for temperature-induced deformations of the production goods
(rails, transport units)
Heat stabilization
for temperatures up to 250°C
Manganese phosphate coating (according to EN ISO 9717)
ensures increased protection against corrosion, good adhesion of lubricants
and better runability
Riveted sheet steel cage
provides high stability at low friction
Sealing options
Steel shields (2ZR)
Viton seals (2VSR) up to a maximum temperature of 250°C
