PLC 110-190 Spherical Roller Bearing for Mixer Reducer Top80


Field Notes on the PLC 110-190 Spherical Roller Bearing for Mixer Reducers

If you maintain concrete mixer gearboxes or heavy-duty reducers, you’ve probably heard of the PLC 110-190 Spherical roller bearing for mixer reducer top 80. I’ve watched this series quietly win trust on shop floors—partly because it just survives abuse. In fact, the “Top 80” mixer reducer niche is tough: shock loads, misalignment, borderline lubrication. This unit leans into that reality rather than pretending conditions are textbook.

Industry trend, quickly

Mixer fleets are pushing longer service intervals and standardizing on C3/C4 clearances with robust EP2 greases. There’s also a gradual shift to higher-purity steels and better surface finishes; surprisingly, that alone can add months of uptime. To be honest, buyers are more pragmatic now—reliability and lead time beat fancy packaging.

Key specifications

Model PLC 110-190 Spherical roller bearing for mixer reducer top 80
Type / Rows Spherical roller, double-row, self-aligning
Bore × OD × Width ≈110 × 190 × 49 mm (real-world use may vary by housing)
Clearance C3 standard; C4 on request
Cage Machined brass (typical), steel option
Dynamic/Static rating Cr ≈ 315 kN; C0r ≈ 300 kN (per ISO 281 calc)
Limiting speed (grease) ≈1,800 rpm (reducers typically run far lower)
Recommended grease NLGI 2 lithium complex EP2, base oil 220 cSt for shock loads
Operating temp -20 to 120 °C (short peaks to 140 °C)

Where it works

  • Concrete mixer reducer (Top 80 configuration), asphalt mixers, aggregate blenders
  • Fertilizer and feed mixers, mining slurry agitating boxes
  • General gear reducers facing misalignment and shock loading

What’s inside (process and testing)

Materials: vacuum-degassed bearing steel (≈100Cr6). Rings are through-hardened; rollers with gradient-hardened profiles for stress distribution.

Methods: CNC turning, multi-stage grinding, logarithmic roller profiling, superfinishing (Ra ≈ 0.05–0.08 μm). Cage pockets deburred by hand—yes, it still matters.

Standards: ISO 492 (P6 by default), ISO 281 life calculations, failure modes per ISO 15243.

Testing: vibration V2 grade, dimensional audit, ferrography on grease run-in, 100% visual/traceability. Typical runout ≤ 5 μm; roundness ≤ 1.5 μm. L10h at 300 rpm and 50 kN radial load: ≈40,000 h (application-dependent, obviously).

Why fleets like it

  • Self-aligning geometry absorbs housing distortions
  • Brass cage tolerates shock and poor lubrication episodes
  • Stable clearance over heat cycles; fewer “mystery” failures

A maintenance lead told me their last batch of PLC 110-190 Spherical roller bearing for mixer reducer top 80 cut Saturday tear-downs in half. Small sample, sure—but it tracks with what I hear elsewhere.

Vendor snapshot (comparative)

Feature Hebei Factory (this model) Generic Market Premium Import
Steel purity High, low inclusion Variable Very high
Heat treatment control Tight, documented Basic Excellent
Lead time Short (stock + build-to-order) Uncertain Moderate
Price Competitive Low High

Customization

  • Clearance: C3/C4; matched sets for paired reducers
  • Cage: brass, steel, or polyamide (for specific duty)
  • Corrosion protection: phosphate or black-oxide
  • Private-label, traceable QR, export packing

A quick case

A regional mixer fleet swapped to PLC 110-190 Spherical roller bearing for mixer reducer top 80 after three mid-season failures. Same grease, better alignment practice, and a mild preload adjustment. Six months later: zero bearing-related stoppages; oil temp dropped ≈6–8 °C. Not a lab, but compelling.

Certifications and origin

Manufactured in: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province. ISO 9001:2015 in place; PPAP packs and material mill certs available on request.
