High-performance SNN Series plummer blocks are highly rigid and easy to handle. They contain NSK's tough spherical roller bearings, which have high load capacity, low temperature rise and high-strength cages

Full-complement cylindrical roller bearings for crane sheaves that are equipped with tight seals intended to prevent intrusion of foreign matter.

Features:

1. Contact seals provide improved sealing capability to prevent the intrusion of foreign matter and water.
2. Large radial and axial capacity is retained for high capacity performance.
3. Phosphate coating provides improved corrosion resistance.
4. Grease can be replenished through the use of inner ring lubrication holes.
5. The number of bearing peripheral parts required for mounting the bearing has been reduced through the use of snap rings on the outer ring.

NSK, the first company in the world to offer sealed roll neck bearings, now offers the Extra-Capacity Sealed-Clean series of roll neck bearings.

Features:

1. Newly designed internal specifications and a new compact seal result in a high-capacity design that provides increased bearing capacity.
2. The new main seal and seal holder are designed for easier mounting and dismounting.
3. The new bore seal prevents the buildup of negative pressure as a measure against water infiltration.
4. Bearing material is made from super-TF steel, which contributes to enhanced bearing life under conditions of contaminated lubrication.

Through the application of NSK's innovative concepts, the EM series bearing has a greater number of larger rollers than that of a conventional bearing. Furthermore, the optimally designed one-piece cage offers high rigidity and low-wear performance.

EW Series Bearing

Features:

1. Bearing life increased by approximately twofold.
2. Noise and vibration levels reduced by 60 to 70 percent.
3. Cage strength has been increased by one and a half to twofold.
4. Limiting speed increased by 10 to 25 percent.

EM Series Bearing

Features:

1. Bearing life increased by approximately twofold.
2. Noise and vibration levels reduced by 40 to 50 percent.
3. Cage strength has been dramatically improved.

NSK developed a series(S-Type)of tough, sealed-clean roller bearings for chain conveyors that must operate under severe conditions They feature newly designed seals (Japanese Utility Model pending) with exceptional effectiveness. These seals, combined with specially formulated grease, assure long life with no maintenance, even at high temperatures and in the presence of water and scale Also, the inner and outer rings are made of case-hardened steel to make them resistant to shock loads for rugged operating conditions, S-Type chain-conveyor bearings are the solution to maintenance problems.
