FRB Bearings have a number of senior engineers and highly qualified technical workers, product performance is stable and reliable, has a perfect quality assurance system and advanced detection means, to ensure product quality long-term stability.

Materials :50Mn or 42CrMo carbon steel, quenching hardness can reach HRC58-64, and quenching hardness is 229-269HB.

Accuracy: P5 precision is suitable for this type. Only when the bearing accuracy is up, can the overall equipment accuracy be guaranteed to run well.

Positioning: The mounting hole of inner and outer ring is used for positioning, easy to install and disassemble.

Double row slewing bearings characteristics : double row slewing bearings has three seats, steel ball and separate can be directly discharged into the upper and lower raceways, and two rows of steel balls with different diameters are arranged according to the force condition.This open assembly is very convenient. The bearing angle of the upper and lower arc raceways is 90 degrees, which can withstand large axial force and overturning moment. The raceway shall be specially designed when the radial force is greater than 0.1 times of the axial force.The axial and radial dimensions of double row slewing bearings are relatively large and the structure is tight.

Double row slewing bearings applications: This series of products are widely used in earthmoving machinery, excavator, dismantling machine, stacking machine, leveling machine, road roller, dynamic rammer, drilling machine, tunneling machine, concrete machine:Concrete pump truck, concrete mixer and placing boom machine belt type cloth machine, disc type feeder, sand mixing machine, wheel crane, crawler crane, portal crane, tower crane, fork crane, gantry crane, percussive reverse circulation drill, rotary drilling rig, impact type rotary drill, the rotating drill, reverse circulation rotary drilling rig, is circulation slewing bearing rig, engineering drilling machine of long spiral, diving engineering drilling machine, machine static pressure pile, pile driver, dredge and so on.

FRB Bearings scrupulously follows the quality policy of "the careful manufacture, to manage attentively, to feel relieved use, warm-hearted service", maximum satisfies the user's needs.

FRB Bearings produce double row slewing bearings models:
DTH1238-1, DTH1450, DTH1710, DTH1790, DTH2000D, DTH2300D, DTH2600C, DTH2800B, DTH2800D, DTH3000A, DTH2900, DTH3200B etc.
