Product Description

This 30204 tapered roller bearing is made of chrome steel and is open on both sides. The inner diameter is 20 mm, the outer diameter is 47 mm, and the depth is 15.25 mm. Single row bearings support radial and axial loads in one direction.​ The race is made of chrome steel for durability and resistance to deformation under heavy loads.​ The bearings are open on both sides for lubrication.​ Static load rating is 27,200 newtons and dynamic load rating is 27,000 newtons. The maximum speed for grease is 8,700 revolutions per minute (rpm). These tapered roller bearings are used in applications such as vehicles, construction equipment and agricultural machinery.​

Rolling bearings use rolling elements to maintain separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: sphere, cylinder, sphere, barrel, needle, spindle or cone. All rolling bearings are open, shielded or sealed.​ Sealed bearings are lubricated with oil or grease at the bearing factory, while open and shielded bearings are designed to be lubricated in place and reapplied periodically based on usage. The shield protects the working parts of the bearing from environmental debris that may be introduced and reduce the speed and life of the ball bearing. Rolling bearings are used in a variety of applications ranging from agricultural machinery to conveyor equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts and aggregate crushers.
