The impact roller (idler) set has physical and chemical properties which are high wear resistance, low friction coefficient, not easy to wear leather strap. It also has the fine self lubrication and not easy to card to die in the bad conditions, antistatic, flame retardant, aging resistance, corrosion resistance. It can withstand repeated impact, vibration, mechanical performance is excellent, light weight, easy installation, no maintenance, low noise(3-7DB), smooth operation. The temperature of using keep in -40°Cto-85°C.
The impact roller (idler) is widely used in the original dock transporting places where dust is bigger and the environment has high corrosive, such as mining,

Impact Roller ( Idler) Components
1. Roller Shell (Steel Tube)
We will use tube speciall for roller,compared with ordinary steel tube, in the following aspects, it has great advantages which can make the roller have minimum radial play eccentricity
Items
Ordinary steel tube
Tube specially for roller
Outside diameter tolerance
± 0.8mm
± 0.3mm
Wall thickness tolerance
± 0.38mm
± 0.1mm
Bending degree
≤ 1.5mm/m
≤ 0.5mm/m
Ovality
≤ 0.6
≤ 0.15
Height of inner bur
+0.5~ -0.2
0
Shaft
We use high precision cold-drawn steel which has high brightness and little tolerance
Bearing
1.We use deep groove ball bearing with big clearance, it’s C3,C4. And this clearance can make rollers revolve flexibly.
2. Bearing type is 2RZ and 2RS with oil seal which have advantage in dust proof.
3. Material: Bearing Steel
4.Specification: 6204/6205/6206/6305/6306/6307/6308/6309/6310
Bearing Housing and Seals
1. Type: DTII, TD75, TK contact and labyrinth seals, TK labyrinth, TKII
2. Bearing Housing material: 08 F with high tensile strength,high hardness,good toughness and easy to be welded and punched not easy to crack
3. For seals, the material we can provide has ABS resin, Nylon, Hdpe, Polyurethane, polyformaldehyde and so on
And it has great advantage in dust proof, water proof which can be used in harsh working conditions
