980811NT is a type of bearing specifically designed for the harsh environments encountered by forklifts and material handling equipment. This bearing boasts outstanding radial load-bearing capacity and durability.
Key Dimensions:
Bore Diameter (d): 55 milímetros
Outer Diameter (D): 80 milímetros
Width (B): 23 milímetros
Load Ratings: Engineered for high radial load capacity. The dynamic load rating (Cr) and static load rating (Cor) are optimized to handle the significant weight and stress encountered in forklift wheel end applications.
Precision & Clearance: Manufactured to standard (P0) or higher precision grades as required, with a radial internal clearance (C3/C4 is common) suitable for the press-fit mounting and thermal expansion typical in drive assemblies.
Cage: Features a high-strength, precision-stamped steel cage. This design ensures precise roller guidance, excellent durability under high-speed and high-load conditions, and contributes to the long service life of the forklift bearing.
R4 is specifically designed to seamlessly integrate with mechanical equipment manufactured according to imperial (inch) dimensions, and is suitable for markets that follow imperial standards.
Especificaciones clave:
Bore Diameter (d): 1/4 inch (0.2500")
Outer Diameter (D): 0.625 inch (5/8")
Width (B): 0.196 inch
Dynamic & Static Load Ratings: Engineered for reliable performance in its size class. The R4 offers a balanced dynamic (Cr) and static (Cor) load capacity suitable for its intended applications.
Speed Ratings: Capable of moderate to high rotational speeds, with specific limits depending on the lubrication condition and operational environment
Internal Clearance: Typically supplied with a standard radial internal clearance (C0/CN) suitable for most common applications. Other clearance groups can be specified for unique thermal or fit requirements.
Sealing/Shielding Options: Supplied as open, or with metal shields (ZZ) or rubber seals (2RS) to retain grease and exclude contaminants.
The MR52 is a high-performance miniature ball bearing, expertly engineered for applications where space is limited but performance is critical.
Especificaciones clave:
Bore Diameter (d): 2 milímetros
Outer Diameter (D): 5 milímetros
Width (B): 1.5 milímetros
Load Ratings: Despite its miniature size, the MR52 is engineered to handle meaningful loads for its scale. Its dynamic (Cr) and static (Cor) load ratings make it suitable for a range of light-duty, high-precision applications. Exact values are detailed in our technical documentation.
Speed Ratings: Capable of very high rotational speeds, which are essential for applications like small DC motors and high-speed spindles in dental or laboratory tools.
