302/28-zz 302/28-2rs Single Row Tapered Roller Bearings
The 302/28 bearing is a tapered roller bearing with an inner diameter of 25 mm , an outer diameter of 58 mm, a width of 16 mm. It typically uses 34000 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
302/28-zz or 302/28-2rs Tapered roller bearings have tapered inner and outer ring raceway, Tapered Roller arranged in between. All conical surface projection lines in the bearing axis of the same point together. This design makes tapered roller bearings particularly suitable to withstand complex (radial and axial) load.Most of the axial load bearing capacity is determined by the contact angle α; α greater the angle, the higher the axial load capacity. The angular size of the calculation of the coefficient e; e higher the value, the greater the contact angle, the bearings are subjected to axial load greater applicability.
