Connecting links

FASING offers wide range of connecting links which are suited to specific performance conditions and the applied chains. The connecting links can work in horizontal position (OZPZR), vertical position (OZBR) or they can work in both positions as universal links (OZUS and OZUZR). The applied, special heat treatment and performed machining in the latest machining centres guarantees increased, more effective, actual mechanical and performance parameters in comparison to the requirements included in DIN 22258 standard. Moreover, it ensures fast and easy assembly and disassembly of connecting links while maintaining the high product quality and its reliability.

! Mechanical properties of the connecting links OZUZR, OZUS, OZPZR, OZBR, which are included in DIN 22258-1, DIN 22258-2, DIN 22258-3 standards and by considering the Rebinder effect, regard the surface after technical production process (without scales) in dry, non-oily condition, without any coatings.

OZUS
Connecting Links Universal Bolt
acc. to DIN 22258-1, PN-G-46705, FASING Technical Requirements and MT-T 99

Application

For connecting round link chains (in vertical and horizontal position), mining flat link chains (in horizontal position only) and other chains upon agreement with FASING. OZUS connecting links undergo qualification testing in 100%. The tests consist of test force application to the links in the value of ~75% to ~90% of breaking force.

Mechanical properties

For all types of connecting links there are appropriate strength grades:
PN-acc. to PN-G-46705, DIN-acc. to DIN 22258-1
and PW, D acc. to FASING Technical Requirements, DIN 22258-1 and PN-G-46705

Acceptable work force and working load limit (DOR, DOE, WLL, WF) should not exceed 70% of breaking force value and should be consistent with appropriate standard DIN 22258-1, DIN 22252 or DIN 22255 for chains and/or consistent with FASING requirements and guidelines. Other chain sizes e.g. 26 x 100, 30 x 120, 34 x 136, 38 x 144 are available following the individual agreements with a customer.

OZPZR
Horizontal Connecting Links
Lock Rapid (fast assembly and disassembly)
acc. to DIN 22258-2 and FASING Technical Requirements

Application

For connecting round link chains, mining flat link chains and others upon agreement with FASING. OZPZR shape adapts it to work in horizontal position only.

! OZPZR Horizontal Connecting Links will operate with conveyor sprockets only if assembled in horizontal plane.
