The LFR50 series U groove track roller bearings (including models LFR50/4-5, 50/5-4, 50/5-5, 50/5-6, LFR50/8-6-2RS) are specialized for industrial guide and transmission scenarios, featuring a U-shaped groove design for stable matching with corresponding guide rails. Available in two material options—high-strength bearing steel (N) and wear-resistant PP engineering plastic—and two seal types (rubber seal for dustproof/waterproof, metal seal for high-temperature resistance), they adapt to diverse working environments. The integrated U-groove structure ensures low-friction rolling and precise positioning, while precision processing enhances wear resistance and service life. Customizable dimensions, seal structures, and groove profiles are supported to meet personalized equipment needs, making them ideal for light-to-heavy load guide mechanisms.
Automated production line guide systems, logistics conveying equipment, textile machinery guide rollers, printing machinery positioning mechanisms, engineering machinery auxiliary guide components, warehouse automation devices, and light-to-heavy load material handling systems
LFR50 Series U Groove Track Roller Bearings (interchangeable with bearings matching "LFR50 model + U-groove structure + corresponding seal/material + size" specifications, including brand equivalents from SKF, INA, and NTN for industrial guide systems)

Q: What’s the difference between rubber seal and metal seal for LFR50 series bearings?
A: Rubber seals excel in dustproof/waterproof performance for general environments, while metal seals resist high temperatures (up to 200℃) for harsh high-heat working conditions.
Q: When to choose bearing steel (N) or PP material for these bearings?
A: Choose bearing steel (N) for heavy-load or high-strength scenarios; PP material is ideal for light-load, corrosion-resistant, or low-noise requirements.
Q: Can LFR50 series bearings be customized with non-standard dimensions?
A: Yes, inner diameter, outer diameter, width, and groove size can be customized to match specific guide rail and equipment installation needs.
