NTN Triple-Sealed Bearings for Bearing Units These reliable triple-sealed bearings are dustproof and waterproof. They ensure a longer bearing life even when exposed to heavy airborne dust and splashes of foul water. Features Better dustproofing and waterproofing ensure a longer bearing life. Triple-sealed bearings feature a secure bearing seal with three lips. This special seal offers reliable dustproofing and waterproofing superior to those of standard bearings used in bearing units. In addition, it ensures a longer service life, even when exposed to heavy airborne dust and splashes of foul water. (Patent pending) Reduces maintenance cost. A bearing life longer than that of a standard bearing unit configurations means extended maintenance intervals, greatly reduced maintenance costs (of inspection, relubrication, replacement, etc.), and increased availability of machinery. Decreases price of the bearing unit and contributes to more compact machinery. The triple-sealed bearing unit replaces conventional covered bearing units in certain operating conditions, greatly decreasing the cost of bearing units. In addition, if the cover is not required, the machinery can be made more compact. Secure balled setscrew The triple-sealed bearing is mounted on the shaft with NTN s unique balled setscrew, which features an embedded ball in its tip. Compared with knurled cup point or cup-point setscrews, the balled setscrew provides much greater resistance to loosening, as it does not readily loosen due to vibration or impact. Interchangeability The triple-sealed bearing unit conforms to the JIS (Japanese Industrial Standard) for UC-type bearings. It is not only ready to use as a relubricable bearing, but it also replaces the conventional bearing units of NTN and other manufacturers. It therefore serves as a ready replacement for existing bearing units. 1
Construction Types Low-torque triple-sealed bearing (Cylindrical-bore, set-screw type) UC21D1LLJ through UC218D1LLJ UC35D1LLJ through UC32D1LLJ High-torque triple-sealed bearing (Cylindrical-bore, set-screw type) UC21D1LLS through UC212D1LLS Outer ring Ball Sealing device The rubber seal extends to the outer circumference the shielded plate for better sealing performance, and prevents contamination of the bearing by dust or foul water. Sealed plate Galvanized steel plate construction ensures improved corrosion resistance. Optimal design contributes to enhanced pressure resistance. (Square-bore type for agricultual machines) 1AS8-11/8, 4AS9-11/4, etc. Inner ring Triple-lip Provides excellent dustproofing and waterproofing, thus protecting against contamination by dust or foul water. Triple-seal Allowable Operating Temperature Range and Speed The triple-sealed bearing can be used in a temperature range of -15 C to 1 C. Allowable speed Low-torque triple-sealed bearing unit dn value : 36 High-torque triple-sealed bearing unit dn value : 21 Typical Applications Triple-sealed bearing units are suitable for machinery used in locations subjected to splashes of foul water and heavy dust, including machinery used in steel-making, casting, garbage disposal, waterworks and sewage treatment, car washers, laundry washing, food processing, fish processing, construction, transportation, agriculture, textiles, and dyeing. Sample application : A pillow unit (right) and a square flange unit (left) are used in a conveyor unit operating in an environment with heavy airborne dust. Special Specifications The standard prelubrication for bearings in this series is Li-mineral grease. Contact NTN Engineering for optional bearings lubricated with Solid Grease (heat-solidified grease) or food-grade grease, or for bearings made of stainless steel. 2
