VA (single lip without double spring),

KA (double lip without double spring),

DA (double lip and double spring)

SA, TA, VA, KA sectional view

B-type inner frame oil seal: including frame, fastening spring, rubber body and auxiliary lip

1. Main features: single-layer outer iron shell design, with better stability and precise equipment characteristics

2. Common types: SB (single lip), TB (double lip)
