The NBL.30.1255.200-1PPN Slewing Bearing Gear is a standard bearing suitable for various applications. It features high speed, cold resistance, corrosion resistance, and heat resistance. The sealing gland is sealed on both sides for maximum protection.
This single-row bearing is designed with a straight raceway and is made of 50mn/42CrMo material. It is a versatile bearing that can bear axial force, radial force, and overturning moment simultaneously.
Samples of this product are available at a minimum order of 1 set for US$0 per set. Customization is also available upon request.
Product Description:
– Four-point contact ball slewing turntable bearings consist of two ring seats. They have a compact structure, light weight, and can bear axial force, radial force, and overturning moment simultaneously. They are widely used in various industries such as lifting transportation and construction machinery.
– Single row cross roller slewing bearings are composed of two or three rings. They have a compact structure, high manufacturing accuracy, and small assembly gap. They can bear axial force, overturning moment, and large radial force simultaneously. They are commonly used in precision products and machinery.
– Double row ball slewing bearings have simple structures and can support high static loads. They are mainly used in situations with variation load position and direction and continuous rotation, such as deck hoisting, mining, and material handling.
– Three-row roller slewing bearings are able to bear all kinds of loads at the same time. They have a firm structure and are suitable for heavy machinery requiring larger diameters, such as bucket wheel stackers and reclaimers, wheel cranes, marine cranes, and port cranes.
