K Series Ball Bearing

Standard : Ball bearing Mounting sizes acc. to DIN ISO 12240-4 dimension series K 
Inner ring : Antifriction bearing steel, hardened, high precision machined.
Housing : Steel with bearing outer ring pressed into housing, raceway precision ground.
Rolling element : Balls made from through-hardened, antifriction bearing steel.
Covering disc : Stainless steel caulked into housing.
Lubrication : The rod ends are given initial lubrication.
Note : With these rod ends, it is important to ensure that the tilt angle speci- fied in the table it not exceeded, either while mounting or during opera- tion, otherwise the cover washers may be damaged.

Max. per-missible speed : This is affected by the bearing load, the bearing clearance, the lubricant and heat output and input.The maximum permissible speed given in the tables applies for apurely radial load, normal bearing clearance tolerance, no external heat, an operating temperature which is not above the limit, and a low and absolutely shock-free load.
Cabricating nipple : Size 6 to10: DIN 3405 Size 12 to 30: DIN 71412
Load ratings : calculated acc. to DIN ISO 76 and 281.
Special versions : available on request
