2.Double row tapered roller bearing outer (or inner) as a whole. Two inner (or outer) face close to the middle spacers, clearance by the thickness of the spacer to adjust, and can also be used to adjust the thickness of spacer double row tapered roller bearings are pre loaded.
3.our tapered roller bearings, such bearings performance and double row tapered roller bearing is basically the same, but more than double row tapered roller bearings withstand higher radial loads, lower speed limits, mainly for heavy machinery, such as rolling machines.
4.Multi-sealed double, four-row tapered roller bearings, ZWZ provide long-life, multi-sealed double, four-row tapered roller bearings. Personalize bearing new design, changing the traditional design methods fully sealed bearings, sealed with a combination of new dust seal structure type, to improve the sealing effect and improve the sealing performance. Multi-sealed double, four-row tapered roller bearings with open structure bearing, life expectancy increased by 20% to 40%; lubricant consumption by 80%.
5.Tapered roller bearings use
Tapered roller bearings mainly bear radial diameter and axial joint load. Load bearing capacity depends on the outer ring raceway angle, the greater the angle Order Greater carrying capacity. These bearings are separable bearings, rolling bearing according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be adjusted during installation the user; double row and four row tapered roller bearing clearance in the factory according to user requirements is given, not to be user adjusted.
6.Tapered roller bearings have tapered inner and outer ring raceway, Tapered Roller arranged in between. All conical surface projection lines are the same point on the bearing axis together. This design makes tapered roller bearings particularly suitable for combined (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle increases, the higher the axial load capacity. Angle size calculation factor e; e larger the contact angle the greater the bearing axial load greater applicability.
7.Tapered roller bearings are usually separated type, namely the belt roller and cage assembly of inner components can be composed with tapered conical outer inner (outer) installed separately.
8.Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
9.Tapered Roller Bearing Installation
Four tapered roller bearing installation (installing roller bearing):
One, four-row tapered roller bearings with inner ring and roll neck band gap is generally installed when the first bearing into the bearing housing, and then put into the journal bearing housing.
Two, four-row tapered roller bearing outer ring and the bearing housing bore also uses dynamic fit, the first outer ring A load bearing box. Factory in the outer ring, inner ring and the inner and outer spacer are printed word {HotTag} symbol in the symbol must be installed according to the order of characters in turn load bearing box. Can not be arbitrarily interchanged, in order to prevent bearing clearance changes.
Third, all parts are loaded into the bearing housing after the inner ring and the inner spacer, outer ring and the outer spacer axial try to be.
Fourth, the measurement face and the bearing outer ring width of the gap between the cover plate to determine the appropriate thickness of the gasket.
Multi-sealed bearings with post code XRS flag.
