Skf Deep Groove Ball Bearing

SKF deep groove ball bearings are one of the most widely used types of rolling bearings, renowned for their high reliability, low friction, and versatility. These bearings are designed to withstand radial loads and moderate axial loads, suitable for high-speed operation scenarios, and offer advantages such as simplified installation and low maintenance requirements. Below is a detailed explanation of their core product features and technical parameters:

Adopt a single-row deep groove raceway design, with precise coordination between the inner/outer ring raceways and steel balls to ensure uniform load distribution.

Standard open-type bearings are available, with variants featuring dust covers (ZZ, 2Z) or seals (2RS1) to effectively block contaminant intrusion.

Retainers can be selected as stamped steel (for light-duty applications) or engineering plastic (suitable for high-speed conditions), reducing friction and temperature rise.

• Size Range: Inner diameters from a minimum of 3 mm to a maximum of 400 mm, covering micro to large industrial needs.
• Precision Grades: Range from P0 (normal grade) to P6/P5 (precision grades) to meet rotational accuracy requirements for different working conditions.
• Speed Capacity: Under grease lubrication, the limiting speed of small and medium-sized bearings can reach 20,000 rpm (e.g., type 608), while large bearings (e.g., 6318) reach approximately 6,000 rpm.
• Dynamic/Static Load Ratio: Typical values such as type 6205 bearing: dynamic load 14 kN, static load 7.85 kN; axial load capacity is approximately 20%-30% of radial capacity.

Manufactured from high-purity chrome steel (GCr15) or stainless steel (SUS440) for special working conditions, with heat treatment processes ensuring a hardness of 58-62 HRC.

• SKF Explorer Series: Life extended by over 50% through optimized heat treatment and surface processing.
• Energy-saving Type (E2): Friction torque reduced by 30%, suitable for high-efficiency motors.

Electric motors (accounting for over 60% of applications), automotive gearboxes, pump equipment, household appliances (e.g., washing machines), and industrial transmission systems.

High-temperature versions (with S1 suffix) can operate long-term in 200℃ environments; food-grade lubrication models comply with FDA standards.

Default filling with lithium-based grease (e.g., SKF LGMT2); synthetic oil lubrication is optional for high-temperature conditions.

Sealed bearings are maintenance-free for life, while open-type bearings require regular lubricant replenishment.

SKF deep groove ball bearings are certified under the ISO 9001 quality management system and provide global warranty services, making them an ideal choice for high-load, long-cycle operation in industrial equipment.
