Angular Contact Ball B. FAG 7334 -B-MP-UA
The single-row FAG angular contact ball bearing 7334 -B-MP-UA with a 170 mm bore can accommodate high radial and unilateral axial loads thanks to its brass cage and 40-degree contact angle.
The FAG 7334 -B-MP-UA angular contact ball bearing is an open, single-row rolling bearing made from standard bearing steel 100Cr6. With key dimensions of a 170 mm bore, 360 mm outside diameter and 72 mm width, this design is suitable for demanding shaft mountings. The raceways, which are offset at an angle to one another, effectively dissipate combined loads. A dimensionally stable brass cage guides the rolling elements at operating temperatures ranging from –20 to +200 degrees Celsius. The component complies with tolerance class P0/PN or ABEC 1.
What is the 7334 -B-MP-UA angular contact ball bearing suitable for?
This angular contact ball bearing is designed for applications where high radial loads and single-sided axial forces occur simultaneously. Due to its nominal contact angle of 40 degrees, the component absorbs these axial loads in a specific direction and supports the mounted shaft against axial displacement in one direction.
As the bearing is designed as an open variant without sealing washers, it can be integrated directly into on-site lubrication circuits. The lubricant reaches the raceways and rolling elements unimpeded, allowing the heat generated during operation to be dissipated.
What does the abbreviation ‘UA’ mean in the context of paired arrangements?
The suffix ‘UA’ denotes a universal bearing that is designed by the manufacturer for installation in pairs. When the 7334 -B-MP-UA angular contact ball bearing is fitted as a bearing pair in an O or X arrangement, a small amount of axial clearance is automatically established. This simplifies installation compared with individual bearings that need to be matched separately.
The outer ring has neither a flange nor a ring groove, which allows it to be slid into a cylindrical housing bore. In conjunction with the standard radial bearing clearance and the solid brass cage, this design ensures that the rolling elements remain stable within the bearing set, even when load directions vary.
What are the dimensions of the 7334 -B-MP-UA angular contact ball bearing?
The bearing has an inner diameter of 170 mm, an outer diameter of 360 mm and a width of 72 mm. These dimensions mean it is one of the large roller bearings used for heavy-duty shaft mountings in mechanical engineering. The outer ring is cylindrical in shape and has neither a flange nor a retaining groove.
What is the purpose of the 40-degree pressure angle?
The contact angle of 40 degrees determines the direction in which forces are transmitted between the inner and outer rings. Thanks to this large angle of 40 degrees, the single-row bearing can accommodate particularly high axial forces in one direction, whilst also supporting radial forces.
What are the features of the brass cage in the MP version?
The abbreviation MP stands for a solid brass cage that guides the balls. Brass cages offer high strength when subjected to vibrations and impact loads. Furthermore, the material retains its stability across the entire temperature range from -20 to +200 degrees Celsius.
What should be borne in mind when fitting a pair of bearings in an O or X configuration?
In the UA version, when mounted in pairs in an O or X configuration, a small amount of axial clearance is created as a result of the design. This eliminates the need for time-consuming manual adjustment of the bearing clearance. For radial guidance, the single bearing has a standard radial clearance.
What type of lubrication does the open angular contact ball bearing require?
The open bearing has no integrated seals. The bearing housing therefore requires an external seal to protect against dirt, as well as continuous lubrication with oil or grease. This ensures that the lubricant reaches the contact surfaces between the balls, the cage and the raceway directly.
What is the operating temperature range for this bearing?
Manufactured from standard roller bearing steel 100Cr6 with a brass cage, the bearing is suitable for operating temperatures ranging from -20 to +200 degrees Celsius. For operation at the temperature limits, the selected lubricant must also be suitable for this temperature range.
