• Needle bearing seals are made of steel rings and special synthetic rubber with a small cross section height.
• Since this seal is made to fit the cross-sectional height of the needle bearing, it is effective to prevent grease leakage and foreign matter from entering by directly incorporating it into the bearing side.
• The OS with a single lip should be used with the lip facing inward to prevent grease leakage and with the lip facing outward to prevent foreign matter from entering.
• The DS with two lips is effective for preventing grease leakage and dust. For preventing grease leakage, use the main lip facing inward, and for preventing foreign matter from entering, use the main lip facing outward.
