Tapered Roller Bearings FAG 30307
The 30307 tapered roller bearing from FAG Wälzlager is a single-row complete bearing measuring 35 × 80 × 22.75 mm, offering a high load-carrying capacity for combined radial and axial loads.
The 30307 tapered roller bearing from FAG Wälzlager is a standard single-row roller bearing designed to withstand high radial forces and single-direction axial forces. With a bore of 35 mm, an outer diameter of 80 mm and a width of 22.75 mm, this roller bearing is suitable for demanding industrial applications. Manufactured to tolerance class P0/PN or ABEC 1, it meets standard requirements for concentricity and fitting accuracy. Thanks to its robust sheet steel cage and wide temperature range of –30 to +120 degrees, the bearing can be integrated in a variety of ways in mechanical engineering and maintenance.
What are the practical applications of the 30307 tapered roller bearing?
Typical applications include gearboxes, wheel bearings, conveyor systems and industrial drive trains where combined loads occur. Truncated conical rollers transmit forces in a linear fashion and ensure high rigidity. As single-row tapered roller bearings, by design, can only accommodate axial forces in one direction, designers often fit these bearings in pairs in a mirror-image arrangement. Whether in maintenance or new design, this component proves its worth wherever reliable power transmission is required.
What are the advantages of the sheet steel cage in the 30307 tapered roller bearing?
The integrated sheet steel cage guides the rolling elements precisely along the raceway of the inner ring and prevents direct contact between the rollers. This cage design retains its dimensional stability even under thermal stress in the range from –30 to +120 degrees and is resistant to typical lubricants. As an open, complete tapered roller bearing, the outer ring can be fitted separately from the pre-assembled inner ring, including the roller cage. This simplifies installation and allows for the precise adjustment of the bearing clearance during fitting onto the shaft.
What are the dimensions of the 30307 tapered roller bearing?
With a bore of 35 mm, an outside diameter of 80 mm and a total width of 22.75 mm, the bearing has standardised key dimensions. These dimensions allow for direct replacement in existing designs. Before installation, it is advisable to check that the shaft diameter and housing bore are dimensionally accurate.
What loads can the single-row bearing withstand?
As a single-row roller bearing, this component simultaneously absorbs high radial and axial forces from a single direction. The tapered arrangement of the rollers diverts the applied forces at an angle to the axis of rotation. To accommodate axial loads in both directions, two bearings are mounted facing each other.
Within what temperature range does the bearing operate reliably?
The bearing is designed for an operating temperature range of -30 to +120 degrees. The robust sheet steel cage and the dimensionally stable bearing rings can easily withstand this temperature range. When commissioning the machine, ensure that the selected grease or lubricating oil is also suitable for your machine’s operating temperature.
What does the designation ‘tolerance class P0/PN’ or ‘ABEC 1’ mean?
The P0/PN and ABEC 1 classifications denote the standard industrial tolerance class for dimensional and running accuracy. Bearings in this class offer tried-and-tested concentricity for most industrial applications in general mechanical engineering. They meet standard requirements without the need for special fits for high-precision spindles.
Can the 30307 tapered roller bearing be dismantled?
Yes, the complete tapered roller bearing consists of a flangeless outer ring and an assembly comprising the inner ring, roller ring and cage. The outer ring can be fitted into the housing separately, whilst the inner ring is slid onto the shaft. This design makes assembly and subsequent inspection considerably easier.
How is the bearing play adjusted during installation?
Single-row tapered roller bearings do not have a factory-set bearing clearance. The operating clearance is only created during assembly by axial alignment against a second bearing. Design engineers use shims, shaft nuts or keyways for this purpose to precisely adjust the required clearance or a defined preload.
