  • Drawn Cup Needle Roller Bearing, Outer Ring
  • On Sale Till 31/03/2025

A bearing in which an outer ring is formed from a thin steel plate by precision drawing, the raceway surface is surface-hardened, and then a needle-shaped roller and a retainer are assembled.
[Features]
・ It has the smallest cross-sectional height of any bearing with an outer ring, enabling space reduction and cost savings.
・ Compact design is possible with the shaft directly as the raceway surface without using the inner ring.
・ The outer ring has a structure in which the needle roller and the retainer are not separated.
・ Retaining rings are not required for fixing in the axial direction by simply press-fitting into a rigid housing with an appropriate fit.
[Applications]
・ Heavy load, high speed, gearbox for automobiles, etc.
・ Steel equipment, mining / construction machinery, machine tools.

Product features details

Shell-type needle roller bearings that can reduce space and cost

It is a bearing in which an outer ring is formed from a thin steel plate by precision drawing, the raceway surface is surface-hardened, and then a needle-shaped roller and a retainer are assembled (as for the part numbers with "M" in the suffix, they are heat treated after assembling). It has the smallest cross-sectional height of any bearing with an outer ring, enabling space reduction and cost savings.
Usually, a design is taken in which the shaft is directly used as the raceway surface without using the inner ring. The outer ring has a structure in which the needle-shaped roller and the retainers are not separated, and the bearing is easy to handle because it does not require a retaining ring to fix it in the axial direction, just by press-fitting it into a rigid housing with an appropriate fit.

Since the suffix T2 uses a polyamide resin molding retainer, the allowable temperature should be 120°C, and 100°C or less for continuous use.
Premium shell bearings have F in the suffix. See CATNO.3029 (Premium Shell Bearing) for details. Those with an M in the suffix are heat-treated products after assembly. (Pre-vent specifications)

The seal type (tailing symbol: L or LL) with a built-in synthetic rubber sealing seal on one side or both sides has lithium soap-based grease sealed inside.
To prevent deterioration of the seal and grease, the operating temperature should be -20 to 120°C, and within 100°C for continuous use.

About allowable rotational speed

The permissible rotational speed is the permissible rotational speed that can be achieved based on the following assumptions.

  • Use under conditions where an appropriate amount of grease recommended by NTN is sealed, and the heat generated by sufficient familiar operation, cooling of the outer cylinder, etc., is removed.
  • Use with constant pressure preload.
