Wheel Bearing NICHE 40x74x40mm Double Row Angular Contact 10 Pack

Description

Product Overview

The NICHE 40x74x40mm double‑row angular contact bearing is engineered for demanding power‑transmission applications. Constructed from GCr15 chrome steel, the bearing offers exceptional hardness, wear resistance, and fatigue strength, ensuring reliable performance even under high radial and axial loads. The rubber seal with integrated spring preserves lubrication while preventing dust, moisture, and other contaminants from entering the bearing cavity, extending service intervals and reducing downtime. With an inner diameter of 40 mm, outer diameter of 74 mm, and a width of 40 mm, the bearing fits a broad spectrum of industrial machinery, including gearboxes, conveyors, and high‑speed spindles. The double‑row configuration provides symmetrical load distribution, enhancing stability and reducing vibration, which translates into quieter operation and lower maintenance costs. Each package contains ten identical units, allowing users to maintain inventory levels and replace worn bearings without delay.

Usage

Designed for heavy‑duty environments, this angular contact bearing excels in applications where precision, durability, and temperature tolerance are critical. It is suitable for use in manufacturing equipment, material handling systems, automotive assembly lines, and any machinery that requires consistent rotational accuracy. The robust seal protects against harsh chemicals, oil splashes, and particulate ingress, making it ideal for factories with high levels of airborne debris. Additionally, the bearing’s low‑noise characteristics benefit settings where acoustic comfort is a concern, such as clean rooms or facilities with strict noise regulations. Engineers and maintenance technicians appreciate the straightforward installation process, as the bearing’s standard dimensions align with common shaft and housing specifications, reducing the need for custom machining.

Why Choose Us

Choosing the NICHE angular contact bearing means investing in a product that combines premium material science with meticulous manufacturing controls. Each bearing undergoes rigorous quality inspections, including dimensional verification, hardness testing, and dynamic balance assessment, guaranteeing conformity to international standards. The use of chrome steel not only provides superior load‑carrying capacity but also resists corrosion, extending the bearing’s operational lifespan even in humid or chemically aggressive environments. Our rubber‑spring seal is engineered to maintain elasticity over a wide temperature range, ensuring consistent sealing performance from sub‑zero to elevated temperatures. Moreover, NICHE offers comprehensive technical support, providing installation guidance, troubleshooting assistance, and after‑sales service to help customers maximize equipment uptime. By selecting this bearing, users benefit from reduced replacement frequency, lower total cost of ownership, and confidence in a product backed by a reputable manufacturer.

FAQ

What size shaft can this bearing accommodate?

The bearing has an inner diameter of 40 mm, so it fits shafts with a nominal diameter of 40 mm. Tolerances are within standard ISO limits, allowing a snug fit without excessive preload.

Can the bearing operate in high‑temperature environments?

Yes. The chrome steel material and rubber‑spring seal are rated for continuous operation up to 120 °C (248 °F), making the bearing suitable for most industrial temperature ranges.

How often should the bearing be lubricated?

Because the seal retains grease effectively, routine lubrication is typically required only during major overhauls or if the bearing is exposed to extreme operating conditions. Follow the manufacturer’s recommended grease type for optimal performance.

Is the bearing compatible with existing equipment housings?

The bearing’s outer diameter of 74 mm conforms to common housing dimensions used in angular contact applications. Verify the housing bore size to ensure a proper fit, but in most cases no modification is needed.

What warranty does NICHE provide?

NICHE offers a one‑year limited warranty covering material and workmanship defects. Customers can contact our support team for warranty claims, replacement parts, or technical assistance.
