Rubber chains – 250×52.5x77N ITR

🔧 Rubber chain for mini excavator and compact track machine 250×52.5x77N

Catalog: RT25052577N

Manufacturer: ITR

Rubber tracks 250×52.5x77N are designed for mini excavators and compact tracked machines of the small class, in which the correct running of the circuit, stable movement and reliable grip are key in everyday work. Size 250×52.5x77N combine width 250 mm, step 52.5 mm, 77 links and N profile, which means, that the choice must be made carefully according to the old circuit, the running gear and the specific machine model. The rubber tracks 250×52.5x77N ITRs are suitable when replacing worn or damaged chains on machines such as the Hitachi ZX22U, Hitachi ZX22U-2, Hitachi ZX22U-3, Hitachi EX20UR-3, Kubota K022, Kubota KX021, Kubota KX61-2, Kubota RX201 и Airmann AX20UR-3, когато се търси правилно напасване, stable water, good grip and reliable operation under daily load.

🔁 Alternative sizes and chains

The size 250×52.5x77N should not be arbitrarily replaced with standard 250×52.5×77, as well as closely sized as 250×52.5x76K, 250×52.5x76N, 250×52.5x78K, 250×52.5x78N, 250×52.5x78W, 250×52.5x74n, 250x48x78, 250x48x80, 250×48.5x84K, 250×48.5x84Y, 250x109x37W, 260×52.5x77N or 300×52.5x77N, without doing an exact check on the old chain and undercarriage.

The letter N is important, because it may indicate a different internal profile, different driver type or specific circuit implementation, rather than simply an alternate spelling of the same size. With this type of rubber track, the profile is just as important, as wide as it is, the step and the number of units.

It is especially important RT25052577N / 250×52.5x77N not to be automatically mixed with RT25052576K / 250×52.5x76K, because the difference is both in the number of units and in the profile. At 76K And 77N the actual length, internal guidance and undercarriage fit may vary.

This size should not be confused with series 250×48, 250×48.5, 250×47 or 250×109, because the pitch difference changes the fit to the sprocket, rollers and running system. Even with the same width, nearby steps and profiles can be completely incompatible, if the number of units or the internal guide do not match.

In some catalogs, the size may be written as 250×52.5x77N, 250×52,5x77N, 250×52.5Nx77, 250×52,5Nx77, 250x77x52.5N or 250x77x52,5N. This does not change the need for physical inspection of the old circuit, because the actual installation depends on the width, step, number of units, profile, driver and specific running system.

Alternatively, OEM/reference codes for this size can be found C0001128, 4675091 And RT25052577N, but before ordering it is recommended that the size and profile on the old chain be physically checked.
