4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Aerospace equipment (slewing of satellite antennas), precision radars, high-end machine tools (grinding machine turntables), optical inspection equipment.
6.Key Inspection Items: Flaw detection of forgings (no internal defects), slewing accuracy, quenching hardness of raceways.

Product Description

High-Precision Cross Roller Ring Bearings for Demanding Industrial Applications

Optimized for extreme loads, precision motion, and harsh environments – trust 30+ years of engineering expertise.

When your equipment requires unmatched rigidity and accuracy, Cross Roller Ring Bearings deliver. These annular bearings feature a seamless forged structure with crossed cylindrical rollers, enabling bidirectional load handling and near-zero deflection. At LUOYANG INNO BEARING, we specialize in customizing products for industries where failure isn't an option – from 150°C steel mills to sub-5μm precision medical scanners.

Why Our Cross Roller Ring Bearings Outperform?

  • Heavy-Load Champions: Withstand static loads up to 200kN and dynamic loads up to 80kN, thanks to 50Mn steel raceways and GCr15 bearing-grade rollers.
  • Precision Engineered: Achieve P4-grade accuracy (<0.002mm runout) through CNC grinding – ideal for CNC turntables and optical alignment systems.
  • Fast Custom Sizes: Get non-standard bearings up to φ5000mm in 30 days (70% faster than industry averages).

Technical Specifications

Parameter Specification
Outer Diameter Range 120mm – 1500mm
Temperature Resistance -50°C to +150°C
Precision Grades P4, P5 (ISO 492)

Where Cross Roller Ring Bearings Excel?

1. Precision Machine Tools
Reduce spindle vibration in CNC grinders with <5μm radial runout bearings. Our low-noise design (<30dB) keeps workshops quiet.

2. Medical Imaging Systems
Non-magnetic AISI 316L stainless steel options ensure MRI compatibility, while P4 precision enables sub-millimeter CT scanner alignment.

3. Heavy-Duty Port Cranes
IP67-sealed bearings with hardened raceways (HRC 60+) withstand saltwater corrosion and 300-ton container loads.

FAQ

Q: Can you make bearings larger than φ3000mm?
A: Yes! We regularly produce custom bearings up to φ5000mm for mining excavators.

Q: How do your bearings handle 500°C environments?
A: We use 42CrMo alloy steel with high-temperature grease (up to 200°C) or graphite-based lubrication for extreme heat.

Q: Do you provide maintenance support?
A: Our IoT monitoring kits predict bearing wear by analyzing vibration trends, reducing unplanned downtime by 65%.

Q: What certifications do you hold?
A: We’re ISO 9001, ISO 14001, and ISO/TS 16949 certified, with materials traceable to mill test reports.
