1. Raw materials are recyclable, therefore, bearings are
environmental and no pollution.
2. bearing: low vibration, low noise, high precision, high rpm,
long service life.
3. Test & Inspection: width, smoothness, roundness, balance,
radial clearance, seismic and the whole
series of inspection.
4. Custom-made: produce non-standard bearings according to
customers' requirements, including design,
shape, color, logo and packaging
HK series needle roller bearing has a closed end and is suitable
for shaft end applications with high dynamic loads. It has a
smaller cross-section than a machined needle roller bearing for use
in restricted mounting spaces. The steel cage provides guidance and
even spacing of the rollers for minimum vibration and noise when
operated at high speeds. The needle rollers are made of
through-hardened, high-carbon chromium steel for durability and

Roller bearings use rolling elements to maintain a separation
between moving parts to reduce rotational friction and support
radial and axial loads. These elements can be one of the following
types: ball, cylindrical, spherical, barrel, needle, spindle, or
tapered. Roller bearings can be open on both ends (a shaft can pass
through) or open on one end and closed on the other. An open end
can be sealed or shielded to protect the bearing from solid
contaminants and moisture that could reduce its lifespan. If an end
is sealed, the sealing component is an elastomer lip that contacts
the shaft. If it is shielded, the shielding is a non-contact lip,
usually made of metal. Rolling bearings are used in a range of
applications from agricultural machinery to conveying equipment,
robotics, dental equipment, elevators, rolling mills, ship rudder
shafts, and aggregate crushers etc.
