Description of angular contact roller bearing LM68149/LM68111 kit

Angular-stop single-row roller bearing LM68149/LM68111 kit golt with tapered rollers and increased load capacity.
Split bearing with an outer ring that is tapered on the inside diameter and an inner double flanged ring that is machined on the
outside diameter for taper rollers, held by a pressed steel cage. Can be used at temperatures from -40 °C to +120 °C. Perceives
radial and axial load in one direction. Increased load capacity compared to similar bearings.

Advantages and disadvantages of roller bearings LM68149/LM68111 kit
A feature of the contact type (linear) helps the bearings:

1.5, twice the tonnage of related ball bearings
guarantee very high support strength
Possibility to reduce the dimensions of the racks
better perceive vibration, shock loads
The disadvantages of roller bearings LM68149/LM68111 kit include:

high requirements for bearing alignment
excessive heat, noise
minimum possible turnover

Types of bearings
Angular contact roller bearings LM68149/LM68111 kit are produced in four types: lead, tapered, 4 and 2 in-line. The design of each type
provides reliability, trouble-free operation and good wear resistance. When choosing a roller bearing, remember the following:

speed
type and parameters of loading
required service life
working conditions
In addition, it is necessary to take into account the noise level, cage type, dimensions of angular contact bearings LM68149/LM68111 kit

Device and use LM68149/LM68111 kit
The best option: the use of this type of roller bearings in combination with other products that compensate for axial stresses.
Angular contact bearings LM68149/LM68111 kit dampen predominantly radial, group loads.

There are closed and open angular contact roller bearings, and devices with small or large cages that hold significant
longitudinal stresses. Bearings LM68149/LM68111 kit are made of steel grade 100Cr6 according to CAE52100. Some models have an alloy cage.
Angular contact bearings usually include a PA cage.

Roller bearings of this type are used in gearboxes, generators, extruders, fans, multipliers, vertical spindles. Bearings
LM68149/LM68111 kit have become an integral part of rotary units in metallurgical, machine-tool, printing, handling equipment.

Application of bearing LM68149/68111kit

Tapered roller bearings consist of an outer ring, an inner ring, rollers and a cage. This bearing contains tapered rollers for its rolling element, which are oriented to the inner ring of the back of the rib on the roller large end face. The racing path surfaces of the inner ring and outer ring and the roller contact surface are designed so that the respective apexes converge at a point on the bearing center line. Bearings are classified into standard, intermediate and steep types, according to their contact angle (α). The larger the contact angle, the greater the resistance of the bearing to axial load.
