Types and characteristics of dust caps and seals
ZZ: steel dust cover
The dust cover is pressed into the outer ring. Grease is rarely exposed and foreign impurities are rarely introduced.
ZZS: steel dust cover with stop ring
The dust cover is fixed on the outer ring. Foreign impurities rarely enter. Usually used in small bearings and thin-walled bearings.
TTS: Teflon seal with stop ring
Teflon seals containing glass fiber are fixed to the outer ring. Usually used in small and thin-walled bearings. After the internal pressure of the bearing changes, the seal can be bent to accommodate it. Suitable temperature is from -100 ℃ to 260 ℃.
2RS: contact rubber seal
Insert the outer ring and touch the inner ring slightly. Prevent the exposure of grease and the entry of external impurities. NBR seals are suitable for temperatures from -40 ° C to 120 ° C. FKM seals are suitable for temperatures from -30 ° C to 230 ° C.
2RU: Non-contact rubber seal
Embedded in the outer ring, without contact with the inner ring, can also play an effective sealing role. NBR seals are suitable for temperatures from -40 ° C to 120 ° C. FKM seals are suitable for temperatures from -50 ° C to 230 ° C.
