  • Drawn Cup Needle Roller Bearing, Outer Ring
  • On Sale Till 31/03/2024

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.

T2: Resin retainer
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.
This type has a shorter roller length and a smaller rated load than the open type with the same dimensions.

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.
