TCV Shaft Oil Seal 100x120x8 for Rexroth A2F500 – Durable

TCV Oil Seal Shaft Oil Seal 1001208 For Rexroth A2F500 Hydraulic Pump Seal Kit Shaft Seal: field-tested notes, specs, and what buyers should know

If you run a Rexroth A2F500, you already know: seal integrity decides whether your day goes smoothly or you’re chasing a weep at the shaft. The TCV Oil Seal Shaft Oil Seal 1001208 For Rexroth A2F500 Hydraulic Pump Seal Kit Shaft Seal is the size many fleets keep on the shelf—because downtime costs real money. I’ve seen it in quarries, on mixers, on road rollers; surprisingly, the same profile handles both dust and splash oil conditions quite well when installed right.

Where it’s used (and why it works)

Designed for hydraulic pumps, travel pumps, rotary pumps, and vertical shafts—especially on hydraulic pumps/motors in earth-moving gear like excavators, road rollers, land scrapers, shovel loaders, self-dumping trucks, and mixer trucks. To be honest, the TCV profile’s secret sauce is simple: a spring-loaded primary lip for oil retention and a dust lip to block contamination. Add a rubber-covered OD for better static sealing in housings that aren’t mirror-finish perfect, and you’ve got a reliable daily driver.

Quick specifications

Process, testing, and data (short version)

Materials: selected NBR/FKM compounds with carbon black, anti-aging additives; stainless garter springs. Methods: precision compression molding, CNC flash trimming, cryogenic deflashing for tight edges, light pre-lube, vacuum packing. Testing: per ISO 6194 and DIN 3760—lip interference check, OD press-fit, hardness (Shore A), spring force, runout tolerance. Bench data from recent lots showed leak rate ≤0.3 mL/h at 90°C and 1,500 rpm; dust lip passed particle ingress test with silica dust to ISO 12103-1 A2 levels (internal lab). Certifications: ISO 9001 quality system; RoHS/REACH compliant materials where specified.

Origin and supply

Manufactured in Development Zone, Julu County, Xingtai City, Hebei Province—an area that’s become a genuine seal-making hub. Lead times are decent; to be honest, freight is the swing factor lately.

Customization options

Material swap (NBR ⇄ FKM), dust-lip geometry tweaks, spring stainless grades, special greases, private labeling. Many customers say the FKM upgrade is worth it for hot climates or bio-hydraulic fluids.

Real-world snippets

• Quarry excavator: swapping to TCV Oil Seal Shaft Oil Seal 1001208 For Rexroth A2F500 Hydraulic Pump Seal Kit Shaft Seal (FKM) extended intervals from ≈8 to 12 months; dust ingress dropped after adding a simple V-ring guard.
• Mixer truck fleet: standard NBR ran two seasons; leak checks showed film only—no drops—after 1,800 hours at average 70°C case temp.

Trends and tips

The market’s nudging toward FKM and better OD coatings as housings age. Watch for counterfeit springs and recycled rubber—easy tell is inconsistent hardness. Install with light oil, avoid lip nicks, and keep shaft Ra around 0.2–0.8 μm; it matters more than people think.

In short: the TCV Oil Seal Shaft Oil Seal 1001208 For Rexroth A2F500 Hydraulic Pump Seal Kit Shaft Seal is a practical, service-friendly choice—especially when paired with clean oil and a decent shaft finish.
