The NTN original bearing UCFL207 Two-bolt flanged unit can mount shafts with Φ35mm diameter. UCFL207 two-bolt flanged units have an UC207 ball bearing installed. NTN Corporation is the most prominent manufacturer of reliable bearings in Japan. The company is one of the largest exporters of bearings worldwide.

Construction

The NTN bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the NTN deep groove ball bearing are used. A duplex seal consisting of a combination of an oil proof synthetic rubber seal and a slinger, unique to NTN, is provided on both sides.

In UC bearing type the inner ring is fastened onto the shaft in two places by set screws.

In UEL and AEL bearing type the inner ring is fastened onto the shaft with the eccentric locking collar system. The inner ring is fastened to the shaft by means of eccentric grooves provided at the side of the inner ring and on the collar.

All bearing types can be mounted on the UCFL pillow block unit.

Re-lubricatable type

The NTN re-lubricatable type bearing unit has an advantage over other similar units being so designed as to permit re-greasing even in the case of misalignment of 2? to the right or left. The hole through which the grease fitting is mounted usually causes structural weakening of the housing. However, as a result of extensive testing, in the NTN bearing unit the hole is positioned so as to minimize this adverse effect. In addition, the re-greasing groove has been designed to minimize weakening of the housing.

Sealing

The sealing device of the ball bearing for the NTN bearing unit is a combination of a heat-resistant and oil-proof synthetic rubber seal and a slinger of an exclusive NTN design. The seal, which is fixed in the outer ring, is steel reinforced, and its lip, in contact with the inner ring, is designed to minimize frictional torque. The slinger is fixed to the inner ring of the bearing with which it rotates. There is a small clearance between its periphery and the outer ring. These two types of seals on both sides of the bearing prevent grease leakage, and foreign matter is prevented from entering the bearing from outside.

Secure fitting

Fastening the bearing to the shaft is effected by tightening the ball-end set screw, situated on the inner ring. This is a unique NTN feature which prevents loosening, even if the bearing is subjected to intense vibrations and shocks.

Cast iron housing

NTN uses gray cast iron as the standard material for cast iron housings. Among metallic materials cast iron has a high damping capacity, which is an ideal characteristic for mechanical components. This means cast iron, exhibits superior performance when absorbing vibration, compared with other materials. Additionally cast iron is suitable for high temperatures of up to 300C.
