NATV and NATV ... PP-bearing roller

NATV series of roller bearing roller with NATR series is basically the same, the only difference is NATV series full complement needle roller type. So it can withstand heavy loads at low speeds, but must pay attention to regular lubrication. NATV ... PP series with seal structure.

NUTR-bearing roller
NUTR series of roller slewing bearing is double row full complement cylindrical roller bearings, the outer ring guided by the ribs. All parts are made of bearing outer ring pressed into the sealing cap to form a complete unit, the sealing cover and the thrust ring together form a highly efficient clearance seal. The wheel bearing can withstand very heavy loads, because the rolling elements with axial guidance, even at high speeds can also withstand the impact of axial loads.

Tolerance
DF-bearing roller curve wheel size, shape and rotation precision usually is P0 level. Diameter with a circular arc curve roller bearing roller diameter tolerance is 0/-0.05mm, NATR, NATV, NUTR bearing width tolerance h12, curve wheel stud diameter tolerance h7.

Adjustable Mind
Diameter cylindrical roller bearing with adjustable concentric small. At low load, it is about 3-4 ', in the medium to high load of 5-7'. With arc-shaped outer concentric bearing wheel adjustable 15-20 '. When a larger angle error, according to the size of the load there is significant edge stresses, it will reduce bearing life.

KR and KR ... PP curve roller
In KR, KR ... PP curve roller, there is a cage-guided needle roller and outer ring on the ring via a bolt axial guidance. For heavy loads and medium speed. Because there is more inside the bearing grease storage space, so lubrication intervals have been extended. KR ... PP curve roller is in contact with the seal structure. Using a temperature of -30 ℃ -100 ℃.

KR and KR ... PP curve roller
KRV and KRV ... PP curve roller KRV and KRV ... PP type curve rollers
KRV, KRV ... PP curve roller and KR, KR ... PP curve roller same structure, only that they are full complement needle roller bearings. They can withstand heavy loads and low speeds. And must always grease.

NUKR curve roller
This series curve roller is double row full complement cylindrical roller structure. Cylindrical roller bearings like the same with the outer ring axially guided by the rolling body pressed into the outer casing and the wall composed of high-level effect of the gap seal.
This curve can withstand particularly high wheel loads, as well as due to the axial roller guide can also withstand the impact of axial load.

KRE, KRE ... PP, KREV, KREV ... PP, NUKRE curve roller
All models are available with eccentric roller curve supply. The end face of the roller bolt grooves can be adjusted. The bolt face marked "HSB" Department said eccentric sleeve highest point.
