Precision Flat Thrust Bearing 15x28x9mm 51102 Thrust Bearing For Small Medium Machinery

Product Description

Precision Flat Thrust Bearing 15x28x9mm 51102

51102 Flat Thrust Bearing 15×28×9mm provides reliable axial support for small to medium machinery. This single-direction thrust ball bearing is essential for mechanical transmission systems including machine tools, construction machinery, and automated equipment.

Basic Dimensions

Inner Diameter (d)	15mm
Outer Diameter (D)	28mm
Thickness (T)	9mm

Structural Features

Features a separable design with three components: shaft washer, housing washer, and steel ball-cage assembly. This design simplifies installation and maintenance while allowing individual component replacement. Note: This bearing accommodates single-direction axial loads only and requires combination with radial support components.

Core Materials

Bearing Rings: High-carbon chromium bearing steel (SAE-52100) with hardness HRC 60-64
Rolling Elements: Precision-ground bearing steel balls with micron-level roundness control
Cages: Nylon (PA66) for standard applications; stamped steel or brass for high-speed/high-temperature conditions

Performance Parameters

Basic Dynamic Load Rating (C)	10.5-10.6 kN
Basic Static Load Rating (C₀)	16.8-18.3 kN
Limiting Speed (Grease)	6200-6700 rpm
Limiting Speed (Oil)	9400-10000 rpm
Temperature Range	-40℃ to 120℃ (extendable to 150℃ with special materials)

Lubrication Requirements

Grease Lubrication: Recommended for speeds ≤6000 rpm. Use lithium-based grease (Grade EP2) filling 1/3-1/2 of bearing space.

Oil Lubrication: Recommended for high-speed (>6000 rpm) or high-load conditions. Use ISO VG32 or VG46 extreme pressure industrial gear oil.

Application Fields

Small and medium-sized mechanical equipment
Dental treatment chairs
Barcode printers
Small elevators
Transmission systems
Reducer output shafts
Motor end cover axial support
Roots pump rotor axial limits
Light industry equipment
Agricultural machinery
Knitting machinery roller shafts
Small tractor hydraulic systems
Canning processing equipment

The 51102 flat thrust bearing combines precise dimensional design with separable construction, high-wear-resistance materials, and stable load-bearing performance, making it ideal for applications requiring high axial support accuracy and space efficiency.
