Use of Estimates, Policy [Policy Text Block]
Use of Estimates:  The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments. These estimates and judgments affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities (if any) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]
Cash and Cash Equivalents:  Cash and cash equivalents include cash in banks and highly liquid investments with original maturities of three months or less.
Accounts Receivable [Policy Text Block]
Accounts Receivable, Net of Allowances:  Allowances are maintained against accounts receivable for doubtful accounts. Allowances for doubtful accounts are maintained for estimated losses resulting from the inability or unwillingness of customers to make required payments. These allowances are based on historical experience, existing economic trends and both recent trends of specific customers estimated to be a greater credit risk as well as general trends of the entire customer pool. Accounts are written off against the allowance when it becomes evident collection will not occur.
Changes in the Company's allowance for doubtful accounts, including write-offs, are as follows:
 20252024
Balance at January 1$6.6 $13.2

Write-offs(0.3)(4.3)
Recoveries(1.6)(4.0)
Foreign currency effect0.2 (0.5)
Balance at December 31$6.8 $6.6 
The allowance for doubtful accounts balance includes allowance of receivables classified as long-term of $4.5 million and $3.9 million in 2025 and 2024, respectively.
Liability Reserve Estimate, Policy [Policy Text Block]
Self-insurance Liabilities:  The Company is generally self-insured for product liability, environmental liability and medical and workers’ compensation claims. For product liability, catastrophic insurance coverage is retained for potentially significant individual claims. The Company also has insurance for certain historic product liability claims. An estimated provision for claims reported and for claims incurred but not yet reported under the self-insurance programs is recorded and revised periodically based on industry trends, historical experience and management judgment. In addition, industry trends are considered within management judgment for valuing claims. Changes in assumptions for such matters as legal judgments and settlements, legal defense costs, inflation rates, medical costs and actual experience could cause estimates to change in the near term.
Advertising Cost [Policy Text Block]
Advertising Costs:  Advertising costs are expensed as incurred. Total advertising expense was $11.5 million, $11.7 million and $10.6 million in 2025, 2024 and 2023, respectively.
Research and Development Expense, Policy [Policy Text Block]
Research and Development Costs:  Expenses associated with the development of new products and changes to existing products are charged to expense as incurred. These costs amounted to $137.2 million, $135.9 million and $119.7 million in 2025, 2024 and 2023, respectively.
Foreign Currency Transactions and Translations Policy [Policy Text Block] Foreign Currency:  Assets and liabilities of non-U.S. operations are generally translated into U.S. dollars at the fiscal year-end exchange rate. The related translation adjustments are recorded as a separate component of equity. Revenues and expenses of all non-U.S. operations are translated using average monthly exchange rates prevailing during the year.
