1, roller bearing press: roller bearing is divided into two, one is stamping bearing, and the other is cast iron (gray iron) bearing. Stamping bearing most of the use of welded steel, cast iron housing are made of steel and extruded. Stamping bearing characteristics are sealed, to withstand strong overall, the biggest feature cast iron housing is concentric high, but low tolerance than bearing press.
2, roller bearings: Bearing is the most important part of the composition of the roller bearing a direct impact on the life of the roller. So choose roller bearings, roller accessories other than select more cautious.
3, seal roller: roller sealing material into polyethylene and nylon. Polyethylene of low cost, but relatively poor wear resistance, on the contrary, the sealing of the relatively high cost of nylon material, but the high abrasion resistance (to identify whether a nylon material, may be sealed into the water, sinking is nylon material sealed, floating in the water is polyethylene material seal). Roller press roller seal species is divided into TD75 type, DTII type, TR-type, TK type, QD80 type, SPJ type, etc. about a dozen. |
