Drawn Cup Needle Roller Bearings Sizes HK2020-2RS

Drawn Cup Needle Roller Bearings Sizes HK2020-2RS

GJP Drawn Cup Needle Roller Bearing is combined with one thin-walled pressed steel outer race (outer shell) plus steel cage and needle rollers, and it’s double seal type with open end, all the needle rollers are produced with chrome steel material at through-hardened process and with four times’ repeated grinding in both end of needle roller. The outer ring of drawn cup needle roller bearings is formed by precision stamping of thin steel plate, with small structural space and large load capacity. It is suitable for occasions where the installation space is limited and the housing hole is not suitable as a raceway.

-Drawn Cup Needle Roller Bearings Sizes HK2020-2RS

GJP Bar Code Number: 6935329838130

GJP Drawn Cup Needle Roller Bearings are combined with one thin-walled pressed steel outer race (outer shell) plus steel cage and needle rollers, and it’s double seal type with open end, all the needle rollers are produced with chrome steel material at through-hardened process and with four times’ repeated grinding in both end of needle roller, through this, it could gurantee the rolling elements not to scratch the slot of cage and maintain good up and down movement for the rollers in cage, for the outer shell, it has a reduced cross-section which could be used in limited spaces, for the cage, normally it’s steel cage, and if there is a letter “TN” mentioning , it stands for nylon cage, the working temperature for this bearing is ranging from -20 degree centrigrate to +120 degree centigrade.

 

Drawn cup needle roller bearings are assemblies, there are two types of open type and closed type. The assembly includes a thin-walled drawn cup, needle roller and cage assembly.

The outer ring of the drawn cup needle roller bearings is formed by precision stamping of thin steel plate, which has a small structure space and a large load capacity. It is suitable for occasions where the installation space is limited and the housing hole is not suitable for the raceway. And no further axial positioning is required after being pressed into the bearing seat hole.

Sealed drawn cup needle roller bearings have a sealing ring seal to protect the bearings from foreign intrusion and grease leakage under normal operating conditions. Therefore, it can operate for a long time within the range of -20°C-120°C operating temperature. It can be used at +130℃ if it can be supplemented with suitable grease in time or in short-term use. The sealing ring is made of synthetic rubber, the lip has good elasticity, and the core is lined with steel plate, which has strong mechanical rigidity. In addition, the sealing ring plays an axial guiding role for the cage.

Features of drawn cup needle roller bearings

  1. Small frictional resistance, low power consumption, high mechanical efficiency, easy to start.
  2. The size is standardized, interchangeable, easy to install and disassemble, and easy to maintain.
  3. The structure is compact, the weight is light, and the axial dimension is further reduced.
  4. High precision, high speed, small wear and long service life.
  5. Some bearings have self-aligning performance.
  6. It is suitable for mass production, with stable and reliable quality and high production efficiency.

 

This HK series bearing is normally assembled directly with one hardened and ground shaft, and also if necessary customers could insert one Bearing Inner Ring firstly into bearing, then assembled with one non-hardened shaft, which the bore could not be used as a raceway for this needle roller bearing assembly, instead there is a very compact and economic bearing arrangement is required.

This GJP drawn cup needle roller bearings are widely used on Construction Machinery, Machine Tools, Automobiles, Metallurgy, Mining, Gearbox, Machinary, Electricity, Railways and Other industries etc.
