Product DetailProduct Description
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.
Type, structure, and features of shell needle roller bearings
| Type | Compatible shaft diameter (mm) | Nominal Number | Composition and dimensions | Note | ||
|---|---|---|---|---|---|---|
| HK (HK・・T2) | Standard Series | Open End | ø3 to ø50 | HK0609T2 | Diameter of Inscribed Circle: ø6 Width dimensions: 9 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) |
| HK・・L | Open End One-sided seal | ø12 to ø50 | HK2018L/3AS | Diameter of Inscribed Circle: ø20 Width dimensions: 18 L: One-sided seal 3AS: Grease | 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. | |

| HMK (HMK・・T2) | Open End | ø8 to ø50 | HMK2015 | Diameter of Inscribed Circle: ø20 Width dimensions: 15 | 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. | |
| HMK・・L | Open End One-sided seal | ø8 to ø50 | HMK2018L/3AS | Diameter of Inscribed Circle: ø20 Width dimensions: 18 L: One-sided seal 3AS: Grease | 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.

| BK (BK・・T2) | Closed End | ø3 to ø50 | BK2020C | Diameter of Inscribed Circle: ø20 Width dimensions: 20 C: Welding 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. | |
| BK・・L | Closed End One-sided seal | ø12 to ø50 | BK2018L/3AS | Diameter of Inscribed Circle: ø20 Width dimensions: 18 L: One-sided seal 3AS: Grease | This seal type (suffix: L) 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 continuous use should be within 100°C. | |
| BK・・ZWD | Closed End Double row type | ø15 to ø30 | BK2030ZWD | Diameter of Inscribed Circle: ø20 Width dimensions: 30 ZW: Retainer double row D: Outer ring lubrication hole | This type has a lubrication hole in the outer ring. | |
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.
