These are the special-purposed seals for needle roller bearings whose cross sectional height is designed so small as to match applicable needle roller bearings. These contact seals are made of synthetic rubber reinforced with steel plate, being then used in operating temperature range of -25 to +120°C and, under continuous running, at 100°C and less. Two different seal types are available: type G with one lip and type GD with two lips. Please feel free to contact our technical support team for the use of these seals under special operating condition, e.g. operating temperature of over 120°C.
