6312 Deep Groove Ball Bearing: Specifications, Performance & Applications

Overview and Key Search Phrases
The 6312 60x130x31 deep groove ball bearing is a robust, single-row, open-type bearing widely used in industrial and mechanical applications. Globally, users search for phrases like “6312 bearing”, “6312 60x130x31”, “deep groove ball bearing 6312”, “bearing 60x130x31”, and “metric deep groove bearing 6312”. This description places those exact and related phrases in strategic positions to help search engines map relevance.

Specifications & Design Details

• Bearing series / model: 6312

• Inner diameter (d): 60 mm

• Outer diameter (D): 130 mm

• Width (B): 31 mm

• Type: Deep groove ball bearing, single row, open (no built-in seals)

• Material: High-grade bearing steel

• Internal clearance: Standard (normal)

• Cage / retainer: Commonly sheet steel or pressed metal

• Typical load rating (example reference from SKF spec): dynamic ~85.2 kN, static ~52 kN

• Limiting / reference speed (open type): ~7000 rpm limit, 11 000 rpm reference per SKF datasheet

• Mass / weight: ~1.72 kg

Because this variant is open (no 2RS / ZZ style), it is typically used in environments where external sealing, lubrication, or protective arrangements are handled by the application design.

Performance & Advantages

• Versatile load capacity: supports radial loads and moderate axial loads in both directions

• Low internal friction: open design, minimal internal sealing, suitable for higher-speed operation when properly lubricated

• Ease of integration: standard ISO dimension 60x130x31 allows interchangeability with many brands and equivalents

• Serviceability: open bearing can be cleaned, re-lubricated, inspected as needed

• Cost-effective: open style avoids the added cost of integrated seals or shields

Common Applications

• Industrial gearboxes and transmissions

• Electric motors and generators

• Pumps, blowers, and fans

• Machine tools and CNC equipment

• Conveyor systems and rolling machinery

• Heavy equipment and agricultural machinery

This 6312 deep groove bearing is often the standard choice in applications where the environment is relatively clean or external seals / housings are used.

FAQ (Frequently Asked Questions)

Q1: What does “6312” refer to?
A1: “6312” is the standard model number: the first digit “6” indicates a deep groove radial ball bearing family in the 63 series, and “312” gives the size class. Here it corresponds to 60 mm bore, 130 mm OD, 31 mm width.

Q2: Is this bearing sealed or open?
A2: This specification describes the open (unsealed) version of 6312, meaning no integrated shields or seals. Sealed variants (e.g., 6312-2RS, 6312-ZZ) exist for contaminated environments.

Q3: Can it operate at high speeds?
A3: Yes, when properly lubricated and mounted, this open 6312 can reach reference speeds around 11 000 rpm, with a limiting speed near 7 000 rpm, per standard bearing datasheets.

Q4: How should this bearing be lubricated?
A4: Since it's open, lubrication must be provided externally—via grease, oil bath, or circulation. Regular maintenance and monitoring are essential for longevity.

Q5: Can it handle axial loads too?
A5: Yes, it supports moderate axial loads in both directions, in addition to its primary radial load capability.
