Kubota RB238-22310 Rubber Crawler Assembly

The Kubota RB238-22310 rubber crawler track is engineered as a direct replacement for the undercarriage system on Kubota U15, KX41-2, and KX41-3 mini excavators. The track assembly utilizes a 230 mm width, 48 mm pitch, and 70 link configuration (230x48x70) to match OEM geometry and sprocket engagement. Construction consists of a high-tensile continuous steel cord carcass encapsulated in an abrasion-resistant rubber compound. The design incorporates forged steel links for positive drive engagement and resistance to link detachment. The rubber compound is formulated for cut and tear resistance in mixed soil and aggregate applications. This part supersedes Kubota OEM numbers RA211-22310, RP851-22310, RD431-22310, RD551-22312, and RD551-22313. It is also interchangeable with Bridgestone OEM supply number 68191-22310 and aftermarket reference RA231-22310. The unit weight is approximately 53 kg per track.
