Hebei lanxin conveying machinery co., ltd. in order to meet the
needs of different customers, develops different quality, different
Our company can produce multi - national standard roller and
bracket, according to customer drawings processing custom
The high-quality roller produced by our company can be used all
year round in harsh environments. It has a wide range of use and
has a service life of more than 30,000 hours warranty period one
year.If there is one bad in the warranty period for quality
problem,we will pay for three for you .
1) The pipe is a special welded pipe for the roller, the
ellipticity is between 0.4mm and 0.6mm, and the radial runout of
the produced roller is 0.7mm or less.
2) shaft is a cold drawn bar for high-precision rollers, which has
good corrosion resistance, strength and hardness. The diameter is
0.01mm larger than the inner diameter of the bearing, and the
tolerance is only >0.01mm, which ensures the tight fit of the
bearing inner sleeve and the shaft to make the bearing rotation
3) The bearing seat is made of high quality cold-rolled steel
plate. After repeated stamping, the wall thickness is uniform, the
precision is high, the smooth and burr-free, the inner diameter of
the bearing seat is directly stamped to the appropriate size of the
bearing. Our company can also be based on customers of different
countries and different standards. Specialized molds are required
to meet the needs of customers.
4) The bearing is a special high-quality double-sealed bearing for
the roller. The bearing has a V-shaped groove, which can play the
role of dustproof and waterproof. The temperature range is from
minus 40 degrees to 180 degrees above zero, which can be extremely
cold (example: Russia, Canada, Finland, Italy and other countries
or very hot countries (such as Saudi Arabia, South Africa, Yemen,
Oman, India, Peru, Colombia and other countries) normal use; can
prevent the grease from seeping out during the operation of the
bearing, to ensure Long-term lubrication of bearings.
5) Sealed to the national standard double labyrinth seal 7 pcs, 4
of which are nylon and 3 pieces of iron, which can be good for
dustproof, waterproof, anti-corrosion, wear-resistant,
cold-resistant and anti-cold The advantages of static electricity.
6) The clip ring is made of 65Mn material with a thickness of
7) The roller shell is specially rust-removed to increase the
adhesion of the anti-rust paint. The high-quality roller is divided
into two kinds of ordinary anti-rust paint and baking paint. The
paint is bright in color, acid and alkali resistant, hard and
