6217 2RS C3 SKF 85x150x28 Deep Groove Ball Bearing

Technical Specifications and Application

Robust Industrial Ball Bearing Unit, Ready for Mounting

The 6217 2RS C3 SKF is a single-row deep groove ball bearing with dimensions 85 mm (bore) x 150 mm (outside) x 28 mm (width). It features a radial internal clearance of C3, allowing for better tolerance of thermal expansion or shaft misalignment in demanding conditions, and is sealed on both sides (2RS) for effective protection against dust, dirt and moisture.

This bearing is engineered to carry both radial and axial loads in both directions, making it suitable for a wide variety of heavy-duty applications. Its sealed design and precision workmanship make this bearing an ideal choice for industrial machinery and production environments where durability, reliability and minimal maintenance are essential.

Key Advantages and Typical Uses

Long Service Life and Versatile Industrial Applications

• High durability and long life — hardened steel rings and balls ensure reliable performance under heavy loads and continue operation even under sustained stress.

• Low maintenance thanks to sealed design — dual rubber seals (2RS) prevent contamination by dust, moisture or debris, reducing maintenance frequency and extending service life.

• Stable performance under varying conditions — C3 radial clearance compensates for thermal expansion or slight shaft deflections, reducing risk of binding or overheating.

• Versatile for multiple applications — ideal for industrial drives, gearboxes, shafts, production machinery, agricultural equipment, heavy-duty conveyors, and any assembly requiring a sealed ball bearing with high load capacity.

• Ready-to-install unit — the bearing comes as a complete unit, enabling quick integration into bearing housings or shaft assemblies (bearing units) without need for additional components, which reduces assembly time and potential for error.

Detailed Description

The 6217 2RS C3 SKF 85x150x28 is a precision-engineered deep groove ball bearing designed to handle challenging industrial loads and environments. Its internal structure — hardened steel races and hardened balls — provides excellent load capacity and resilience. With a radial internal clearance C3, the bearing accommodates thermal expansion and minor shaft misalignment without compromising performance, which is particularly important in industrial machinery, conveyor systems, gear units, and mechanical drives.

Thanks to the double rubber seals (2RS), the bearing is protected from ingress of dust, dirt, moisture and other contaminants. This results in reduced wear, lower maintenance intervals and extended service life — a key advantage for applications where downtime is costly or accessibility for maintenance is limited.

This bearing supports both radial and axial loads in both directions, offering versatility in how it can be applied. Whether used in horizontal shafts, vertical spindles, rotating drums or gearboxes — the 6217 2RS C3 SKF delivers smooth, reliable operation, minimizes friction and contributes to energy efficiency in mechanical systems.

As a ready-to-install unit, this bearing simplifies procurement and assembly. It matches the 85x150x28 mm specification precisely, making it a dependable option for retrofits, replacements or new builds where exact dimensions and sealed protection are required.

For companies seeking a high-quality, low-maintenance ball bearing solution for industrial or manufacturing equipment — this 6217 2RS C3 SKF bearing stands out by combining durability, low friction, versatility and ease of installation.

FAQ - Frequently Asked Questions

Q: What type of loads can this bearing handle?
A: The 6217 2RS C3 SKF can handle both radial and axial loads in either direction, making it suitable for shafts, gearboxes, conveyors and other rotating components.

Q: Does the sealed (2RS) version require frequent maintenance?
A: No — the sealed 2RS design protects internal elements from dust and moisture, significantly reducing maintenance frequency compared with open bearings.

Q: Why is the C3 clearance important?
A: C3 clearance provides extra space inside the bearing to accommodate thermal expansion, shaft deflection or load-induced deformation, preventing binding and extending bearing life in demanding conditions.

Q: In which types of machines is this bearing commonly used?
A: It is widely used in industrial machinery, manufacturing equipment, conveyors, agricultural machines, gear drives, shafts, and any mechanical assembly requiring a robust,
