Cross Roller Bearing Guide

Cross Roller Bearing Guide provides multi-directional rigidity by arranging cylindrical rollers at 90° angles between V-grooved raceways. This structure enables uniform load support across radial, axial, and moment directions, maintaining structural stability under complex loading conditions. Cross Roller Bearing Guide remains dimensionally stable even under high moment stresses, making it suitable for compact, multi-axis platforms.

Rail Length

Rail Width

15–100 mm (±0.02 mm), Common – 30 mm, 45 mm, 60 mm

Rail Height

20–120 mm (±0.03 mm), Height-to-Width Ratio – 0.8–1.2

Accuracy Grade

N (Normal – ±0.05 mm/m), P (Precision – ±0.02 mm/m), SP (Ultra-Precision – ±0.01 mm/m)

Bearing Block Type

Single Block, Double Block, or Flanged (with Mounting Holes M6–M12)

Product Description

Cross Roller Bearing Guide ensures minimal elastic deformation through full-line contact of rollers, which significantly improves motion repeatability. Unlike point-contact systems, the distributed contact surface reduces micro-vibrations and positional drift. Cross Roller Bearing Guide maintains consistent path accuracy critical for ultra-precision machines and fine-alignment stages. 

Material

Rails – Carbon Steel (SUJ2, 58–62 HRC), Stainless Steel (440C, 55–58 HRC)

Load Capacity

Static (Co) – 10–200 kN, Dynamic (Ca) – 5–100 kN (e.g., 30mm Rail – Ca ≈ 15 kN)

Preload

Zero (C0), Light (C1 – 2–5% Ca), Medium (C2 – 5–8%), Heavy (C3 – 8–12%)

Operating Temp. Range

–20°C to +120°C (Standard), –40°C to +150°C (Special Grease/Seals)

Certification Standard

ISO 14728 (Linear Motion Guides), JIS B 1504 (Roller Bearings), ISO 9001

Technical Advantages

Cross Roller Bearing Guide can be preloaded to eliminate internal clearance, resulting in higher stiffness and positioning accuracy. Precision-ground raceways and matched components allow controlled preload without generating excessive internal stress. Cross Roller Bearing Guide resists rotational displacement and preserves alignment geometry under varying loads. 

Cross Roller Bearing Guide offers linear and uniform friction characteristics due to the absence of recirculating elements. The orthogonal roller design minimizes fluctuations in rolling resistance, eliminating stick-slip behavior. Cross Roller Bearing Guide ensures stable velocity profiles during continuous scanning or slow feed motion.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure precision tolerance control in Cross Roller Bearing Guides during manufacturing?

Frigate utilizes precision grinding machines to finish raceways within micron-level tolerances. Each Cross Roller Bearing Guide undergoes strict dimensional inspection to maintain parallelism and surface finish. This ensures minimal play and consistent preload application. The result is enhanced repeatability and positional accuracy in critical applications. 

What materials and heat treatment processes does Frigate apply to improve the durability of Cross Roller Bearing Guides?

Frigate uses high-grade bearing steel with optimized carbon content for hardness and fatigue resistance. Advanced heat treatments like vacuum carburizing create a hardened surface layer while preserving core toughness. This process minimizes wear and extends service life under cyclic loading. Cross Roller Bearing Guides from Frigate withstand demanding operational environments with consistent performance. 

 

How does Frigate address lubrication challenges for Cross Roller Bearing Guides used in vacuum or cleanroom conditions?

Frigate offers solid lubricant coatings and dry-film lubrication options to eliminate contamination risks. These lubricants provide low friction without outgassing or particle generation. Custom lubrication solutions are tested to meet vacuum compatibility and ISO cleanroom standards. This ensures reliable motion without compromising sensitive manufacturing environments. 

How does Frigate validate the dynamic load capacity of Cross Roller Bearing Guides for high-speed precision machines?

Frigate conducts rigorous life-cycle testing with simulated operational loads and speeds. Vibration analysis and friction measurements track guide behavior under dynamic conditions. Data from these tests confirm that Cross Roller Bearing Guides maintain stiffness and low friction over millions of cycles. This guarantees dependable performance in high-speed automation. 

In what ways does Frigate customize Cross Roller Bearing Guides to suit specific application moment load requirements?

Frigate adjusts roller diameter, raceway geometry, and preload settings to optimize moment load capacity. Finite element analysis guides design modifications to enhance stiffness in targeted directions. Custom manufacturing processes ensure the guides meet precise load and rigidity specifications. This tailored approach supports complex multi-axis motion systems effectively.
