Product Description

1311 Self Aligning Ball Bearing Low Friction Mining Machinery Bearings Double Row

1311 Self-Aligning Ball Bearing: Low Friction, High Performance

Product Overview

As a key component in mechanical transmission systems, the 1311 self-aligning ball bearing provides reliable performance for stable equipment operation. This bearing effectively handles alignment problems during shaft installation and operation by automatically adjusting angular deviation, ensuring smooth and efficient equipment performance across industrial production, agricultural machinery, and transportation applications.

Structural Design

Double-row Steel Balls and Spherical Raceways: Features two rows of high-precision steel balls with outer ring spherical raceways and inner ring deep groove raceways. This design provides excellent self-aligning capability to handle shaft deflection and installation errors, reducing stress and wear while extending equipment lifespan.
Cage Construction: Utilizes either steel plate stamping cages for high-load conditions or nylon 6,6 snap-type cages (TN9 type) for high-speed applications. The nylon cages offer excellent self-lubrication, wear resistance, and reduced energy loss while maintaining stable operation.

Dimensional Specifications

Dimension Type	Dimension Value (mm)
Inner Diameter (d)	55
Outer Diameter (D)	120
Width (B)	29
Weight	Approximately 1.66kg (varies slightly with manufacturing processes and materials)

Performance Advantages

High-Speed Stability: Low rolling resistance enables stable operation at reference speeds up to 9500r/min with minimal heat generation, making it ideal for high-speed motors and precision machine tool spindles.
Light Load Performance: Low friction characteristics ensure efficient transmission even under light loads, preventing rolling element slippage in applications like textile machinery and automated production lines.
Low Friction Operation: Unique design and quality materials reduce contact point friction, lowering energy consumption and extending bearing service life while reducing operational costs.
Self-Aligning Capability: Accommodates angular misalignment between 1° and 2.5°, automatically adjusting to shaft deflection and installation deviations to maintain shafting operation and prevent equipment failure.

Application Fields

Textile Machinery: Ensures stable operation of spindles and rollers, maintaining yarn uniformity and fabric quality while reducing downtime and improving production efficiency.
Agricultural Machinery: Withstands complex operating conditions in tractors and combine harvesters, adapting to shaft misalignment and impact loads in harsh environments.
Conveying Equipment: Automatically compensates for shaft misalignment in belt and chain conveyors, preventing belt deviation and chain jamming while improving material handling efficiency.
Small Motors: Handles vibration and misalignment in household appliances and office equipment, reducing noise, improving energy efficiency, and extending motor lifespan.
