Deep Groove Ball Bearings SKF 6307 -2RS1
The SKF 6307-2RS1 deep groove ball bearing, measuring 35x80x21 mm, is protected against the ingress of dirt and loss of lubricant thanks to its double-sided lip seals.
The single-row deep groove ball bearing 6307 -2RS1 accommodates radial loads as well as axial forces in both directions. Manufactured from standard rolling bearing steel 100Cr6, this bearing is characterised by its dimensional stability and load-carrying capacity. The seals, which run on both sides, retain lubricant inside the bearing and repel particles and moisture. With an inner ring designed for a 35 mm shaft diameter, an 80 mm outer diameter and a width of 21 mm, the component fits into standardised designs.
What is the 6307-2RS1 deep groove ball bearing suitable for?
This rolling bearing is primarily used on rotating shafts subject to combined radial and axial loads. Whether used as a fixed or floating bearing, the design ensures reliable operation of components at medium to high speeds. Thanks to the sheet steel cage and double-sided sealing, the unit is suitable for operating environments exposed to dust or splashing water.
The standardised tolerance class P0/PN (ABEC 1) allows for straightforward installation in standardised bearing seats. The operating temperature range is specified as -20 to +120 degrees.
What protection does the 2RS1 seal provide?
The 2RS1 seal, which makes contact on both sides, lies directly against the contact surfaces of the inner ring and shields the rolling element set from external influences. The grease applied at the factory remains inside the bearing, whilst foreign particles are prevented from entering the raceway. Compared with open bearing variants, this sealed design reduces the maintenance required.
In combination with the standard radial bearing clearance, the bearing is suitable for operating conditions with uniform temperature distribution without extreme thermal expansion of the shaft. The cylindrical outer ring, without a groove or flange, allows for installation in through-bore housings.
What are the dimensions of the 6307-2RS1 deep-groove ball bearing?
With a bore diameter of 35 mm, an outside diameter of 80 mm and a width of 21 mm, this roller bearing complies with the standardised 6307 series. This geometry fits directly into standardised housing bores and onto cylindrical shaft seats in mechanical engineering.
What does the suffix code 2RS1 mean?
2RS1 denotes contact seals fitted on both sides. The elastic sealing lips run in contact with the inner ring. This ensures that the grease remains sealed inside the bearing, whilst keeping dirt particles and splash water away from the rolling elements and raceways.
What does the standard radial clearance for this deep-groove ball bearing indicate?
The standard radial bearing clearance defines the specified internal clearance between the balls and raceways when the bearing is not installed. This design is suitable for standard applications with typical fits and moderate heating, where there is no significant thermal differential expansion between the inner and outer rings.
Within what temperature range can the bearing be operated?
The permissible operating range is from -20 to +120 degrees Celsius. This range allows for use in numerous standard industrial applications. The temperature limits are determined by the thermal resistance of the lubricant and the sealing material, whilst the rolling-bearing steel retains its dimensional stability even at lower temperatures.
What materials are the cage and bearing rings made of?
The inner ring, outer ring and balls are made from standard 100Cr6 rolling bearing steel with high fatigue strength. The rolling elements are guided by a sheet steel cage, which keeps the balls at a uniform distance from one another and aids load distribution within the raceway system.
Which tolerance class does the SKF 6307-2RS1 correspond to?
Manufactured to tolerance class P0/PN (equivalent to ABEC 1), the bearing meets the standard requirements for dimensional and radial runout accuracy. This classification ensures a precise fit in standardised bearing seats and facilitates interchangeability during maintenance and repair work.
