Single-Row Crossed Roller Slewing Bearing - HJ Series

The HJ Series Single-Row Crossed Roller Slewing Bearing, developed by a specialized rotary bearing manufacturer, features a crossed cylindrical roller arrangement. It offers high precision and rigidity, capable of simultaneously withstanding axial forces, radial forces, and overturning moments.

1. Core Product Features

>Crossed Roller Design

Cylindrical rollers arranged at 90° cross angles enable simultaneous support of axial forces, radial forces, and overturning moments, delivering superior overall performance compared to single-row ball bearings.

High Rigidity Structure

a. Integrated dual-ring design maximizes space utilization

b. Large contact area between raceways and rollers ensures high load capacity

c. Ring material: 50Mn/42CrMo hardened steel (hardness HRC55-62)

d. Roller material: GCr15 bearing steel; retainer made of aluminum alloy/nylon

2. Compliance with International Standards

3. Typical Application Scenarios and Payload Comparison

4. Installation and Maintenance Guidelines

>Installation Requirements:

a. Base frame flatness tolerance ≤ Ra12.5

b. Bolt preload set to 70% of material yield strength (spring washers prohibited)

c. Lubrication cycle: Replenish grease every 50 operating hours; relubricate after prolonged downtime

5. Supplier Services

a.Customization Capability: Supports non-standard dimensions/load requirements

b.Technical Support: Provides installation guidance and post-sales maintenance plans

>Optimization Notes

1. Structural Optimization: Added international standard comparison tables and application scenario load comparison charts for intuitive technical parameter display.

2. Terminology Simplification: Replaced specialized terms with “rotary drive” (e.g., “overturning moment” changed to “tilting moment”).

3. Emphasis Enhancement: Prominently feature international standard compliance and typical application scenarios upfront for quick access to key information.
